barryCentric float barryCentric(Vector3F p1, Vector3F p2, Vector3F p3, Vector2F pos): *
clamp T clamp(T x, T min, T max): * Clamp x in [min, max].
degrees T degrees(T x): * Convert from radians to degrees.
fract T fract(real x): * Returns fractional part of x.
ilog2 int ilog2(T i): * Integer log2.
inverseSqrt T inverseSqrt(T x): * SSE approximation of reciprocal square root.
isPowerOf2 bool isPowerOf2(T i): * Returns true of i is a power of 2.
lerp S lerp(S a, S b, T t): * Linear interpolation.
lfloor long lfloor(real x): * Integer flooring.
ltrunc long ltrunc(real x): * Integer truncation.
moduloWrap T moduloWrap(T a, T b): * Signed integer modulo a/b where the remainder is guaranteed to be in [0..b], even if a is negative. * Only supports positive dividers.
nextPowerOf2 int nextPowerOf2(int i): * Computes next power of 2.
nextPowerOf2 long nextPowerOf2(long i): * Computes next power of 2.
radians T radians(T x): * Convert from degrees to radians.
safeAcos T safeAcos(T x): * Safe acos. Input clamped to [-1, 1].

sinOverX T sinOverX(T x): * Computes sin(x)/x accurately.
smoothStep T smoothStep(T a, T b, T t): *
step T step(T edge, T x): * If x < edge => 0.0 is returned, otherwise 1.0 is returned.
