pub const fn new(array: [f64; 8]) -> Self

pub fn simd_eq<Rhs>(self, other: Rhs) -> <Self as CmpEq<Rhs>>::Output

where Self: CmpEq<Rhs>,

Test if each element is equal to the corresponding element in other.

pub fn simd_ne<Rhs>(self, other: Rhs) -> <Self as CmpNe<Rhs>>::Output

where Self: CmpNe<Rhs>,

Test if each element is not equal to the corresponding element in other.

where Self: CmpLt<Rhs>,

Test if each element is less than the corresponding element in other.

pub fn simd_gt<Rhs>(self, other: Rhs) -> <Self as CmpGt<Rhs>>::Output

pub fn blend(self, t: Self, f: Self) -> Self

pub fn abs(self) -> Self

pub fn signum(self) -> Self

pub fn floor(self) -> Self

pub fn ceil(self) -> Self

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

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

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

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

pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval unless it is NaN.

If self is NaN, or min is NaN, or max is NaN, the result is NaN. If min > max, the result is min, since fast_max(min) dominates.

pub fn fast_clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval unless it is NaN.

Avoids NaN detection; same speed as the old clamp prior to IEEE 754-2019 compliance. Does not specify any behavior if NaNs are involved, and if min > max the result is unspecified.

pub fn round(self) -> Self

pub fn fast_round_int(self) -> i64x8

pub fn round_int(self) -> i64x8

pub fn trunc(self) -> Self

pub fn fast_trunc_int(self) -> i64x8

Truncates each lane into an integer. This is a faster implementation than trunc_int, but it doesn’t handle out of range values or NaNs. For those values you get implementation defined behavior.

pub fn trunc_int(self) -> i64x8

Truncates each lane into an integer. This saturates out of range values and turns NaNs into 0. Use fast_trunc_int for a faster implementation that doesn’t handle out of range values or NaNs.

pub fn fract(self) -> Self

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

Performs a multiply-add operation: self * m + a

When hardware FMA support is available, this computes the result with a single rounding operation. Without FMA support, it falls back to separate multiply and add operations with two roundings.

Platform-specific behavior

• On x86/x86_64 with AVX-512F+FMA: Uses 512-bit vfmadd (single rounding, best accuracy)
• On x86/x86_64 with AVX-512F only: Uses (self * m) + a (two roundings)
• Other platforms: Delegates to f64x4 (inherits its FMA behavior)

Examples

let a = f64x8::from([1.0; 8]);
let b = f64x8::from([2.0; 8]);
let c = f64x8::from([10.0; 8]);

let result = a.mul_add(b, c);

let expected = f64x8::from([12.0; 8]);
assert_eq!(result, expected);

pub fn mul_sub(self, m: Self, s: Self) -> Self

Performs a multiply-subtract operation: self * m - s

When hardware FMA support is available, this computes the result with a single rounding operation. Without FMA support, it falls back to separate multiply and subtract operations with two roundings.

Platform-specific behavior

• On x86/x86_64 with AVX-512F+FMA: Uses 512-bit vfmsub (single rounding, best accuracy)
• On x86/x86_64 with AVX-512F only: Uses (self * m) - s (two roundings)
• Other platforms: Delegates to f64x4 (inherits its FMA behavior)

Examples

let a = f64x8::from([10.0; 8]);
let b = f64x8::from([3.0; 8]);
let c = f64x8::from([5.0; 8]);

let result = a.mul_sub(b, c);

let expected = f64x8::from([25.0; 8]);
assert_eq!(result, expected);

pub fn mul_neg_add(self, m: Self, a: Self) -> Self

Performs a negative multiply-add operation: a - (self * m)

When hardware FMA support is available, this computes the result with a single rounding operation. Without FMA support, it falls back to separate operations with two roundings.

Platform-specific behavior

• On x86/x86_64 with AVX-512F+FMA: Uses 512-bit vfnmadd (single rounding, best accuracy)
• On x86/x86_64 with AVX-512F only: Uses a - (self * m) (two roundings)
• Other platforms: Delegates to f64x4 (inherits its FMA behavior)

Examples

let a = f64x8::from([4.0; 8]);
let b = f64x8::from([2.0; 8]);
let c = f64x8::from([10.0; 8]);

let result = a.mul_neg_add(b, c);

let expected = f64x8::from([2.0; 8]);
assert_eq!(result, expected);

pub fn mul_neg_sub(self, m: Self, s: Self) -> Self

Performs a negative multiply-subtract operation: -(self * m) - s

When hardware FMA support is available, this computes the result with a single rounding operation. Without FMA support, it falls back to separate operations with two roundings.

Platform-specific behavior

• On x86/x86_64 with AVX-512F+FMA: Uses 512-bit vfnmsub (single rounding, best accuracy)
• On x86/x86_64 with AVX-512F only: Uses -(self * m) - s (two roundings)
• Other platforms: Delegates to f64x4 (inherits its FMA behavior)

let b = f64x8::from([2.0; 8]);

let result = a.mul_neg_sub(b, c);

let expected = f64x8::from([-9.0; 8]);
