Module math 

The scalar and vector primitives the rest of the vocabulary is built from: the f32 transcendentals core leaves to a math library, and the 3-component vector ops every layout and transform reaches for.

Modules

vec3

The crate’s shared 3-component vector math. Every module that needs a dot, cross, or component-wise op reaches for these rather than redeclaring them.

Functions

acos

Arc cosine, in radians.

asin

Arc sine, in radians.

atan2

Arc tangent of y / x, in radians, using both signs to pick the quadrant.

ceil

Smallest integer at or above x.

cos

Cosine of an angle in radians.

exp

e raised to x.

exp2

2 raised to x.

floor

Largest integer at or below x.

fract

Fractional part, keeping the sign of x.

hypot

Length of the hypotenuse of a right triangle with legs x and y, without the intermediate overflow of sqrt(x * x + y * y).

ln

Natural logarithm.

log2

Base-2 logarithm.

mul_add

x * y + z with a single rounding.

powf

x raised to n.

powi

x raised to the integer power n, by squaring. Matches the expansion f32::powi lowers to rather than routing through powf, which would round differently.

rem_euclid

Least nonnegative remainder of x (mod rhs).

round

Nearest integer, with halves rounded away from zero.

sin

Sine of an angle in radians.

sin_cos

Sine and cosine of an angle in radians.

sqrt

Square root.

tan

Tangent of an angle in radians.

trunc

Integer part, discarding the fraction and keeping the sign of x.
