Fixed Trigonometry

No-STD fixed-point implementation of trigonometric functions in Rust.

It utilizes the fixed library to allow flexibility in fixed point sizes and precisions.

The package.

The documentation.

Release notes are found under RELEASES.md.

Functionality

The library currently implements:

  • fft/ifft calculation, for complex fixed-point vectors.
  • sin and cos using low order polynomails, for real fixed-point numbers.
  • atan using numerical methods.
  • sqrt using the Nonlinear IIR Filter (NIIRF) method.
  • powi and complex::powi calculation.
  • no-std utilities for complex numbers.
