Module math 

Deterministic elementary functions.

f64::sin and friends call the platform’s math library, whose results differ in the last bit between Windows, Linux, macOS and WebAssembly. Everything that feeds stored geometry, solver iterations, exported files or the scene goes through these wrappers (the pure-Rust libm), so the same input gives the same bits on every platform (DL-TEST-6). sqrt is correctly rounded everywhere and stays f64::sqrt.

Functions

acos

Arccosine.

atan

Arctangent.

atan2

Four-quadrant arctangent of y / x.

cos

Cosine.

hypot

sqrt(x² + y²) without undue overflow.

log2

Base-2 logarithm.

sin

Sine.

sin_cos

(sin x, cos x).

tan

Tangent.
