Crate crlibm[−][src]
Expand description
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.);Functions
