//! Thin wrappers around `libm` free functions so `f32` math works in `no_std`.
//!
//! In `std` builds these compile down to the same instructions as the inherent methods (the compiler sees thru the `libm` call). In `no_std` builds they provide software implementations of the standard math functions.
