Mish

A libm-ish program. It provides most of the functions of libm in pure #![no_std] Rust. Note that it is completely unoptimised, using +-*/ and loops only.

Documentation is missing, but most of the signatures are the same as std, so use those docs instead.

Most functions have been checked, consider increasing the amount of iterations and validating before using for applications where accuracy is critical.

This is a proof of concept, and for most of the functions, they only work within a range. This is not intended to be a replacement for libm. For that, look to something like m.

Using

Add this to your Cargo.toml

mish = "0.2.0"

add this to your crate root

extern crate mish;

and import all functions

use mish::*;

Modules

• funcs is where all of the functions are located, all inner functions have been re-exported here
  • m contains a majority of the mathematical functions
  • n deals with the floating point numbers themselves
  • o has some basic operations
  • t contains the trig functions
    • inv contains the inverse trig functions
    • t contains the trig functions
    • h contains hyperbolic functions
    • hinv contains inverse hyperbolic functions

Note: All functions with iterative methods have a counterpart, not included in prelude, that end with _. These methods have an extra integer (i32 or usize) argument, which specifies the amount of iterations to run for. This can be used to specify precision vs speed of execution. The methods included by default are wrappers with a default value for the loop iterations.
