Struct std::num::diy_float::Fp [] [src]

pub struct Fp {
    pub f: u64,
    pub e: i16,
}
Unstable (core_private_diy_float)

: internal routines only exposed for testing

A custom 64-bit floating point type, representing f * 2^e.

Fields

f
Unstable (core_private_diy_float)

: internal routines only exposed for testing

The integer mantissa.

e
Unstable (core_private_diy_float)

: internal routines only exposed for testing

The exponent in base 2.

Methods

impl Fp

fn mul(&self, other: &Fp) -> Fp

Unstable (core_private_diy_float)

: internal routines only exposed for testing

Returns a correctly rounded product of itself and other.

fn normalize(&self) -> Fp

Unstable (core_private_diy_float)

: internal routines only exposed for testing

Normalizes itself so that the resulting mantissa is at least 2^63.

fn normalize_to(&self, e: i16) -> Fp

Unstable (core_private_diy_float)

: internal routines only exposed for testing

Normalizes itself to have the shared exponent. It can only decrease the exponent (and thus increase the mantissa).
