Turns are Better than Radians (2022)
Summary
Turns are Better than Radians argues for removing radians from many trig computations and using a 0-1 turn domain instead, showing how this can simplify code and improve precision and performance. The piece walks through practical implications, including how common libraries implement sin, the exactness of certain angle representations, and real-world examples from game engines and SIMD implementations, and it suggests migration strategies for libraries that currently rely on radians.
