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.

Most of the Trig functions are from a CORDIC implementation, apart from sin, cos and tan, which are done using a Taylor series to the term of x^7

Hyperbolic trig functions are still missing at the moment.

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

Most functions have been checked to 4 d.p. with a Casio Scientific Calculator, consider increasing the amount of iterations and validating before using for applications where accuracy is critical.

Modules

• funcs is where all of the functions are located
  • 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 (at root: (angle_shift and cbrt))
    • consts contains the loop up tables for inv
    • inv contains the inverse trig functions
    • t contains the trig functions
• prelude is where most users should import from
  • f32 contains all functions for f32
  • f64 contains all functions for f64

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.
