Floating-point code is from compiler_builtins = "0.1.87" and libm = "0.2.6", and has been rewritten for use in a constant context.
Some fuzzing of operations is performed to ensure correctness of the port, but please open an issue if there is any inconsistent behavior.
Features:
* no_std
* const_trait_impl
* const_mut_refs
On stable:
const fn const_f32_add(a: f32, b: f32) -> f32 {
SoftF32(a).add(SoftF32(b)).to_f32()
}
On nightly with const_trait_impl usage:
const fn const_f32_add(a: f32, b: f32) -> f32 {
(SoftF32(a) + SoftF32(b)).to_f32()
}
On nightly with const_mut_refs usage:
const fn const_f32_add(a: f32, b: f32) -> f32 {
let mut x = SoftF32(a);
x += SoftF32(b);
x.to_f32()
}
