WebApr 6, 2024 · 5th Order Polynomial Fixed-Point Sine Approximation. Here is a simple fixed-point approximation to sin (and cos) appropriate for embedded systems without dedicated floating-point hardware. It is accurate to within ±1/4096 (0.01% Full-Scale). No lookup-table is required, and portable C code is available.
