Compact fixed-point math library for embedded systems. 4KB flash, zero dependencies, any radix.
Integer-only fixed-point math with caller-selectable binary point. Provides trig (sin, cos, tan, atan2), log/exp, sqrt, hypot, wave generators (sqr, tri, saw, pwm, noise), ADSR envelope, and 2D transforms. Pure C (C99), works on AVR, ESP32, RP2040, Cortex-M, RISC-V, MSP430, and any board with a C compiler. No floating-point hardware or libraries required.
