Struct RationalInteger 

pub struct RationalInteger { /* private fields */ }

Implementations

impl RationalInteger

pub fn try_new(numer: BigInt, denom: BigInt) -> Result<Self, NumericFailure>

pub fn from_i64_pair(numer: i64, denom: i64) -> Self

pub fn from_bigint_strings( numer_str: &str, denom_str: &str, ) -> Result<Self, NumericFailure>

Construct from string-parsed BigInts (used by SerializedFactor round-trip).

pub fn is_integer(&self) -> bool

pub fn numer_is_zero(&self) -> bool

pub fn numer_is_positive(&self) -> bool

pub fn numer_is_negative(&self) -> bool

pub fn numer_to_i32(&self) -> Option<i32>

pub fn numer_to_i128(&self) -> Option<i128>

pub fn numer_to_u8(&self) -> Option<u8>

pub fn numer_to_usize(&self) -> Option<usize>

pub fn numer_to_string(&self) -> String

pub fn denom_to_string(&self) -> String

pub fn numer_magnitude_bits(&self) -> u64

Exact bit length of the numerator’s magnitude; 0 for zero.

pub fn denom_magnitude_bits(&self) -> u64

Exact bit length of the denominator’s magnitude.

pub fn try_reduce_ref( rational: &RationalInteger, ) -> Result<Self, NumericFailure>

pub fn try_reduce(self) -> Result<Self, NumericFailure>

pub fn try_cmp(&self, other: &Self) -> Result<Ordering, NumericFailure>

pub fn try_to_decimal(&self) -> Result<Decimal, NumericFailure>

Round to Decimal::MAX_SCALE precision.

Returns NumericFailure::Overflow only when |self| > Decimal::MAX.

All RationalInteger values are constructed in reduced form, so no re-reduction is needed here.

pub fn try_to_decimal_string(&self) -> Result<String, NumericFailure>

pub fn display_str(&self) -> String

Human-readable decimal when try_to_decimal succeeds; fraction string on magnitude overflow.
