Struct D307 

#[repr(transparent)]
pub struct D307<const SCALE: u32>(pub Int1024);

Scaled fixed-point decimal with 1024-bit storage. See D38 for the shape documentation; D307 has the same surface scaled to a 1024-bit signed integer and MAX_SCALE = 307.

Gated behind the d307 (or umbrella wide) Cargo feature. The storage backend is Int1024.

Implementations

impl<const SCALE: u32> D307<SCALE>

pub const SCALE: u32 = SCALE

The decimal scale of this type, equal to the SCALE const-generic parameter. One LSB of storage represents 10^-SCALE. Use in type-level / const contexts; prefer Self::scale when an instance is in hand.

pub const ZERO: Self

The additive identity. Stored as zero bits.

Precision

N/A: constant value, no arithmetic performed.

pub const ONE: Self

The multiplicative identity. Stored as 10^SCALE bits.

Precision

N/A: constant value, no arithmetic performed.

pub const MAX: Self

The largest representable value: the storage type’s MAX.

Arithmetic that overflows this bound panics in debug builds and wraps in release builds.

pub const MIN: Self

The smallest representable value: the storage type’s MIN.

Mirror of Self::MAX. Note that -MIN panics in debug builds because two’s-complement MIN has no positive counterpart.

pub const fn from_bits(raw: Int1024) -> Self

Constructs from a raw storage bit pattern.

The integer is interpreted directly as the internal storage: raw represents the logical value raw * 10^(-SCALE). This is the inverse of Self::to_bits.

Precision

Strict: all arithmetic is integer-only; result is bit-exact.

pub const fn to_bits(self) -> Int1024

Returns the raw storage value.

The returned integer encodes the logical value self * 10^SCALE. This is the inverse of Self::from_bits.

Precision

Strict: all arithmetic is integer-only; result is bit-exact.

pub const fn multiplier() -> Int1024

Returns 10^SCALE, the factor that converts a logical integer value to its storage representation. Equals the bit pattern of Self::ONE.

Precision

Strict: all arithmetic is integer-only; result is bit-exact.

Overflow

10^SCALE overflows the storage type at SCALE > MAX_SCALE. Calling with an overflowing scale panics at compile time when the const item is evaluated.

pub const fn scale(self) -> u32

Returns the decimal scale of this value, equal to the SCALE const-generic parameter. The value is determined entirely by the type; the method exists for ergonomic method-call syntax.

impl<const SCALE: u32> D307<SCALE>

pub fn mul_with(self, rhs: Self, mode: RoundingMode) -> Self

Multiply two values of the same scale, rounding the scale-narrowing step according to mode. Result is within 0.5 ULP for the half-* family and bounded by the directed-rounding rule otherwise.

For SCALE ≤ 38 the divide-by-10^SCALE step routes through the Möller-Granlund magic-divide kernel shared with D38 — avoiding the generic schoolbook divide for the common case. Larger scales fall through to the slower n / (10^SCALE) path.

pub fn div_with(self, rhs: Self, mode: RoundingMode) -> Self

Divide two values of the same scale, rounding the scale-narrowing step according to mode. Within 0.5 ULP for the half-* family.

The divisor here is the runtime operand rhs.0, not 10^SCALE, so the MG magic-divide doesn’t apply; the final step uses the wide integer’s schoolbook limbs_divmod (which has its own hardware fast paths for sub-word divisors). Scaling the numerator uses the type’s multiplier() const (already evaluated at the $Storage width) widened to $Wider, avoiding the per-call pow(SCALE) on the wider type.

impl<const SCALE: u32> D307<SCALE>

pub const fn checked_add(self, rhs: Self) -> Option<Self>

Checked addition. Some(self + rhs), or None if the sum would overflow Self.

pub const fn wrapping_add(self, rhs: Self) -> Self

Wrapping addition. self + rhs modulo the storage type’s MAX − MIN range.

pub const fn saturating_add(self, rhs: Self) -> Self

Saturating addition. Clamps to Self::MIN / Self::MAX on overflow.

pub const fn overflowing_add(self, rhs: Self) -> (Self, bool)

Overflowing addition. Returns (self.wrapping_add(rhs), overflowed).

pub const fn checked_sub(self, rhs: Self) -> Option<Self>

Checked subtraction. Some(self - rhs), or None if the difference would overflow Self.

pub const fn wrapping_sub(self, rhs: Self) -> Self

Wrapping subtraction.

pub const fn saturating_sub(self, rhs: Self) -> Self

Saturating subtraction. Clamps to Self::MIN / Self::MAX on overflow.

pub const fn overflowing_sub(self, rhs: Self) -> (Self, bool)

Overflowing subtraction. Returns (self.wrapping_sub(rhs), overflowed).

pub const fn checked_neg(self) -> Option<Self>

Checked negation. Some(-self), or None when self == Self::MIN (whose negation is unrepresentable in two’s-complement).

pub const fn wrapping_neg(self) -> Self

Wrapping negation. Self::MIN.wrapping_neg() == Self::MIN (same as i128::wrapping_neg).

pub const fn saturating_neg(self) -> Self

Saturating negation. Self::MIN.saturating_neg() == Self::MAX.

pub const fn overflowing_neg(self) -> (Self, bool)

Overflowing negation. Returns (self.wrapping_neg(), overflowed); overflowed is true only when self == Self::MIN.

pub const fn checked_rem(self, rhs: Self) -> Option<Self>

Checked remainder. Some(self % rhs), or None if rhs == 0 or the operation would overflow (the pathological case Self::MIN % -ONE).

pub const fn wrapping_rem(self, rhs: Self) -> Self

Wrapping remainder. Panics on divide-by-zero (matches i128::wrapping_rem).

pub const fn overflowing_rem(self, rhs: Self) -> (Self, bool)

Overflowing remainder. Returns (self.wrapping_rem(rhs), overflowed); overflowed is true only at the Self::MIN % -ONE boundary.

impl<const SCALE: u32> D307<SCALE>

pub fn checked_mul(self, rhs: Self) -> Option<Self>

Checked multiplication. Computes self * rhs rounded toward zero, returning None if the result doesn’t fit in Self. The intermediate product is computed in $Wider so widening overflow is detected before the final narrowing.

pub fn wrapping_mul(self, rhs: Self) -> Self

Wrapping multiplication. Computes self * rhs modulo the storage type’s MAX − MIN range. The intermediate product still widens to $Wider; only the narrowing step wraps.

pub fn saturating_mul(self, rhs: Self) -> Self

Saturating multiplication. Computes self * rhs, clamping to Self::MIN / Self::MAX on overflow. Sign of the saturated bound matches the sign of the exact mathematical product.

pub fn overflowing_mul(self, rhs: Self) -> (Self, bool)

Overflowing multiplication. Returns the wrapped result together with a boolean flag — true if the mathematical product was out of range.

pub fn checked_div(self, rhs: Self) -> Option<Self>

Checked division. Returns None if rhs is zero or the result would overflow Self. Rounded toward zero. The numerator is pre-multiplied by 10^SCALE in $Wider so the intermediate carries the scale-up step without losing precision.

pub fn wrapping_div(self, rhs: Self) -> Self

Wrapping division. Computes self / rhs with the scale-up step done modulo $Wider’s range and the final narrowing wrapping. Panics on divide-by-zero (matches i128::wrapping_div semantics).

pub fn saturating_div(self, rhs: Self) -> Self

Saturating division. Computes self / rhs, clamping to Self::MIN / Self::MAX on overflow. Divide-by-zero saturates to the appropriate-sign bound.

pub fn overflowing_div(self, rhs: Self) -> (Self, bool)

Overflowing division. Returns the wrapped result together with a boolean flag — true if the exact quotient was out of range or rhs was zero.

impl<const SCALE: u32> D307<SCALE>

pub const fn abs(self) -> Self

Returns the absolute value of self.

Note: abs(MIN) overflows (because |MIN| has no positive counterpart in two’s complement). Debug builds panic; release builds wrap.

pub fn signum(self) -> Self

Returns the sign of self encoded as a scaled Self: -ONE, ZERO, or +ONE.

pub const fn is_positive(self) -> bool

Returns true if self is strictly greater than zero.

pub const fn is_negative(self) -> bool

Returns true if self is strictly less than zero.

impl<const SCALE: u32> D307<SCALE>

pub fn min(self, other: Self) -> Self

The lesser of self and other.

pub fn max(self, other: Self) -> Self

The greater of self and other.

pub fn clamp(self, lo: Self, hi: Self) -> Self

Restrict self to the closed interval [lo, hi]. Panics if lo > hi.

pub fn recip(self) -> Self

Multiplicative inverse: ONE / self. Panics on self == ZERO.

impl<const SCALE: u32> D307<SCALE>

pub fn copysign(self, sign: Self) -> Self

Magnitude of self with the sign of sign. Zero sign is treated as positive (the storage type has no negative zero).

impl<const SCALE: u32> D307<SCALE>

pub fn unsigned_shr(self, n: u32) -> Self

Logical (zero-fill) right shift of the raw storage by n bits. Unlike the arithmetic Shr operator, the vacated high bits are always zero regardless of sign.

pub fn rotate_left(self, n: u32) -> Self

Rotate the raw storage left by n bits.

pub fn rotate_right(self, n: u32) -> Self

Rotate the raw storage right by n bits.

pub fn leading_zeros(self) -> u32

Number of leading zero bits in the raw storage.

pub fn trailing_zeros(self) -> u32

Number of trailing zero bits in the raw storage.

pub fn count_ones(self) -> u32

Population count of the raw storage.

pub fn count_zeros(self) -> u32

Number of zero bits in the raw storage.

pub fn is_power_of_two(self) -> bool

true if the raw storage, viewed as unsigned, is a power of two.

pub fn next_power_of_two(self) -> Self

Smallest power of two >= the raw storage viewed as unsigned. Panics in debug builds on overflow.

impl<const SCALE: u32> D307<SCALE>

pub fn div_euclid(self, rhs: Self) -> Self

Euclidean division: the quotient as an integer multiple of ONE, chosen so the remainder is non-negative. Panics on rhs == ZERO.

pub fn rem_euclid(self, rhs: Self) -> Self

Euclidean remainder: self - rhs * self.div_euclid(rhs), always non-negative when rhs != ZERO. Both operands share the scale, so no rescaling is needed. Panics on rhs == ZERO.

pub fn abs_diff(self, rhs: Self) -> Self

Absolute difference |self - rhs|. Computed as max - min so the subtraction is always non-negative.

pub fn midpoint(self, rhs: Self) -> Self

Midpoint of self and rhs without intermediate overflow, rounding toward negative infinity. Uses the branch-free (a & b) + ((a ^ b) >> 1) identity, which is overflow-free and storage-agnostic.

pub const fn is_nan(self) -> bool

Always false — a fixed-point decimal has no NaN.

pub const fn is_infinite(self) -> bool

Always false — a fixed-point decimal has no infinity.

pub const fn is_finite(self) -> bool

Always true — every fixed-point decimal value is finite.

pub fn mul_add(self, a: Self, b: Self) -> Self

self * a + b. Mirrors the f64::mul_add call shape so f64-generic numeric code can monomorphise to a decimal type; there is no hardware FMA — the multiply uses the type’s Mul and the add uses its Add.

impl<const SCALE: u32> D307<SCALE>

pub fn div_floor(self, rhs: Self) -> Self

Floor-rounded division: floor(self / rhs) as an integer multiple of ONE. Panics on rhs == ZERO.

pub fn div_ceil(self, rhs: Self) -> Self

Ceil-rounded division: ceil(self / rhs) as an integer multiple of ONE. Panics on rhs == ZERO.

pub fn is_zero(self) -> bool

true if self is the additive identity.

pub fn is_normal(self) -> bool

Returns true for any non-zero value. A fixed-point decimal has no subnormals, so zero is the only value that is not “normal”.

impl<const SCALE: u32> D307<SCALE>

pub fn sqrt_strict(self) -> Self

Correctly-rounded square root.

Negative inputs saturate to Self::ZERO, matching the f64-bridge saturate-not-panic policy of the narrow tiers.

Precision

Strict: integer-only; the result is the exact square root correctly rounded to the type’s last place (within 0.5 ULP).

pub fn cbrt_strict(self) -> Self

Correctly-rounded cube root.

Defined for the whole real line: cbrt(-x) == -cbrt(x).

Precision

Strict: integer-only; the result is the exact cube root correctly rounded to the type’s last place (within 0.5 ULP).

pub fn sqrt(self) -> Self

Square root. With strict enabled this is the integer-only, correctly-rounded Self::sqrt_strict.

pub fn cbrt(self) -> Self

Cube root. With strict enabled this is the integer-only, correctly-rounded Self::cbrt_strict.

pub fn hypot_strict(self, other: Self) -> Self

sqrt(self² + other²) without intermediate overflow, computed integer-only via the correctly-rounded Self::sqrt_strict. Uses the scale-trick algorithm:

hypot(a, b) = max(|a|,|b|) · sqrt(1 + (min(|a|,|b|)/max(|a|,|b|))²)

The min/max ratio lies in [0, 1], so ratio² + 1 is always in [1, 2] — the inner sqrt never overflows. The outer multiply by large only overflows when the true hypotenuse genuinely exceeds the type’s range.

hypot(0, 0) = 0 (bit-exact); hypot(0, x) = |x|.

impl<const SCALE: u32> D307<SCALE>

Natural logarithm (base e). Strict: integer-only and correctly rounded. Panics if self <= 0.

pub fn ln_strict_agm(self) -> Self

Natural logarithm via the Brent–Salamin AGM (1976). Strict and correctly rounded. Same contract as Self::ln_strict; the implementation path differs. AGM converges quadratically and scales better than the artanh-series path at very high working scales.

Currently an alternate; the canonical ln_strict stays on the artanh path until a bench at the relevant working scale shows AGM winning by the OVERRIDE_POLICY.md margin.

pub fn exp_strict_agm(self) -> Self

e^self via Newton’s iteration on ln_fixed_agm. Strict and correctly rounded. Same contract as Self::exp_strict; the implementation path differs. Quadratic convergence makes this asymptotically faster than the Taylor exp_strict at very high working scales.

pub fn log_strict(self, base: Self) -> Self

Logarithm of self in the given base, as ln(self) / ln(base). Strict and correctly rounded. Panics if self <= 0, base <= 0, or base == 1.

Base-2 logarithm. Strict and correctly rounded. Panics if self <= 0.

pub fn log10_strict(self) -> Self

e^self. Strict and correctly rounded. Panics if the result overflows the representable range.

2^self, as exp(self · ln 2). Strict and correctly rounded. Panics if the result overflows.

pub fn powf_strict(self, exp: Self) -> Self

self raised to the power exp, as exp(exp · ln self). Strict and correctly rounded. A zero or negative base saturates to ZERO (a negative base with a fractional exponent is not real-valued).

pub fn sin_strict(self) -> Self

Sine of self (radians). Strict and correctly rounded.

pub fn cos_strict(self) -> Self

Cosine of self (radians), as sin(self + π/2). Strict and correctly rounded.

pub fn atan2_strict(self, other: Self) -> Self

Four-quadrant arctangent of self (y) and other (x), in radians, in (−π, π]. Strict and correctly rounded.

pub fn sinh_strict(self) -> Self

Hyperbolic sine, as (eˣ − e⁻ˣ)/2. Strict and correctly rounded.

pub fn cosh_strict(self) -> Self

Hyperbolic cosine, as (eˣ + e⁻ˣ)/2. Strict and correctly rounded.

pub fn tanh_strict(self) -> Self

Hyperbolic tangent, as sinh / cosh. Strict and correctly rounded.

pub fn asinh_strict(self) -> Self

Inverse hyperbolic sine, as sign · ln(|x| + √(x² + 1)). Strict and correctly rounded. For |x| ≥ 1 the radicand is factored to keep x² inside the working width.

pub fn acosh_strict(self) -> Self

Inverse hyperbolic cosine, as ln(x + √(x² − 1)), defined for x ≥ 1. Strict and correctly rounded. For x ≥ 2 the radicand is factored to keep x² in range.

pub fn atanh_strict(self) -> Self

Inverse hyperbolic tangent, as ln((1+x)/(1−x)) / 2, defined for |x| < 1. Strict and correctly rounded. Panics if |self| >= 1.

pub fn to_degrees_strict(self) -> Self

Convert radians to degrees: self · (180 / π). Strict and correctly rounded. Panics if |self| · 180 overflows the working integer.

pub fn to_radians_strict(self) -> Self

Convert degrees to radians: self · (π / 180). Strict and correctly rounded. mul is the scale-aware (a * b) / 10^w, so the working-width budget is the same as any other binary op in the core — no separate overflow check needed.

pub fn powi(self, exp: i32) -> Self

Signed integer exponent. For non-negative exp this is self.pow(exp as u32); for negative exp it is Self::ONE / self.pow(exp.unsigned_abs()).

pub fn to_int_with(self, mode: RoundingMode) -> i64

Converts to i64 using the supplied rounding mode for the fractional discard step. Saturates to i64::MAX / i64::MIN when the rounded integer is out of i64 range.

impl<const SCALE: u32> D307<SCALE>

Constructs from an f64 using the supplied rounding mode. Saturation policy as in Self::from_f64.

pub fn rescale_with<const TARGET_SCALE: u32>( self, mode: RoundingMode, ) -> D307<TARGET_SCALE>

Rescales to TARGET_SCALE using the supplied rounding mode.

• TARGET_SCALE == SCALE: bit-identity.
• TARGET_SCALE > SCALE: scale-up multiplies by 10^(TARGET - SCALE); lossless; panics on overflow.
• TARGET_SCALE < SCALE: scale-down divides by 10^(SCALE - TARGET) with the requested rounding rule.
