softfp 0.1.0 - Docs.rs

//! Software floating point operation library.
//!
//! Many floating operations require a rounding mode and can set a few exception flags.
//! This library therefore expects two callbacks, `softfp_get_rounding_mode` and
//! `softfp_set_exception_flags`. You can define them with `#[no_mangle]`. The calling
//! convention is Rust, so there is no need for `extern "C"`.
//!
//! If you prefer not to define these callbacks with `#[no_mangle]`, you can use the
//! enabled-by-default "register" feature which allow you to register the function
//! via [`register_get_rounding_mode`] and [`register_set_exception_flags`] instead.
//! You must register them before using the library for any floating point operations.
//! The simplest way would be track them using
//! [`thread_local!`](https://doc.rust-lang.org/nightly/std/macro.thread_local.html)
//! variables.
