 * **Caution:** Due to the introduction of libc math functions in v4.0.0 and the
 * resulting name/behavior clashes between the modulo logic in JS, C & GLSL,
 * this function previously _was_ called `fmod`, but going forward has been
 * renamed to align w/ its GLSL version and exhibits a different behavior to the
 * current {@link fmod} function.
