Crlibm
This crate is a binding to CRlibm, an efficient and proved correctly-rounded mathematical library. For the user convenience, this module embeds the relevant C code from the CRlibm Git repository.
Note that the C code of CRlibm is mature but superseded by MetaLibm (repository) and will therefore not receive updates.
Example
use crlibm::*;
let x = sinpi_rd(2.);
let y = sinpi_rn(2.);
let z = sinpi_ru(2.);
lib.rs
:
Binding to CRlibm, a library of proved correctly-rounded mathematical functions.
Each function, for example “sin”, comes in four flavors depending on how the result is rounded:
sin_rn
: round the result to nearest;sin_ru
: round the result (up) to +∞;sin_rd
: round the result (down) to -∞;sin_rz
: round the result toward 0.
Example
use crlibm::*;
let x = sinpi_rd(2.);
let y = sinpi_rn(2.);
let z = sinpi_ru(2.);
