Floating-point code is from compiler_builtins = "0.1.94"
and libm = "0.2.6"
, and has been rewritten for use in a constant context.
Fuzzing of all operations is performed against the relevant reference code to ensure correctness of the port, but please open an issue if there is any inconsistent behavior.
Exported Soft Float Types:
SoftF32
SoftF64
Features:
no_std
- Enabled by defaultconst_trait_impl
- For const operator implementationsconst_mut_refs
- For const operator with assignment implementationsOn 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()
}
