MicroMath

Mircomath is Embedded-friendly (i.e. no_std) Rust math library featuring fast, safe floating point approximations for common arithmetic operations, trigonometry, 2D/3D vector types, statistical analysis, and quaternions.

It optimizes for performance and small code size at the cost of precision.
