Struct halfpoint_rs::Half

pub struct Half { /* fields omitted */ }

The 16 bit floating point number (half-precision floating-point). Type half can represent positive and negative numbers whose magnitude is between roughly 6.1e-5 and 6.5e+4 with a relative error of 9.8e-4; numbers smaller than 6.1e-5 can be represented with an absolute error of 6.0e-8. All integers from -2048 to +2048 can be represented exactly.

Conversions from half to float are lossless; all half numbers are exactly representable as floats.

Conversions from float to half may not preserve a float's value exactly. If a float is not representable as a half, then the float value is rounded to the nearest representable half. If a float value is exactly in the middle between the two closest representable half values, then the float value is rounded to the closest half whose least significant bit is zero.

Overflows during float-to-half conversions cause arithmetic exceptions. An overflow occurs when the float value to be converted is too large to be represented as a half, or if the float value is an infinity or a NAN.

Methods

impl Half

fn min_exponent() -> i32

fn max_exponent() -> i32

fn min_exponent_10() -> i32

fn max_exponent_10() -> i32

fn epsilon() -> f32

fn min() -> f32

fn min_normalized() -> f32

fn max() -> f32

fn new() -> Half

fn round(&self, precision: u32) -> Half

Round to n-bit precision (n should be between 0 and 10). After rounding, the significand's 10-n least significant bits will be zero.
