warp.copysign

warp.copysign(x: Float, y: Float) → Float

Kernel

Differentiable

Return a value with the magnitude of x and the sign of y.

For example, wp.copysign(3.0, -1.0) returns -3.0 and wp.copysign(-3.0, 1.0) returns 3.0. Useful for forcing a specific sign on a result whose signed-zero behavior is otherwise implementation-defined (e.g. wp.min(-0.0, +0.0)).
