Trevor Gross cc2874c9a9 Add scalbnf16, scalbnf128, ldexpf16, and ldexpf128
Use the generic `scalbn` to provide `f16` and `f128` versions, which
also work for `ldexp`.

This involves a new algorithm for `f16` because the default does not
converge fast enough with a limited number of rounds.

libm

A port of MUSL's libm to Rust.

Goals

The short term goal of this library is to enable math support (e.g. sin, atan2) for the wasm32-unknown-unknown target (cf. rust-lang/compiler-builtins). The longer term goal is to enable math support in the core crate.

Already usable

This crate is on crates.io and can be used today in stable #![no_std] programs.

The API documentation can be found here.

Benchmark

The benchmarks are located in crates/libm-bench and require a nightly Rust toolchain. To run all benchmarks:

cargo +nightly bench --all
