SDL_copysignf

Copy the sign of one floating-point value to another.

Header File

float SDL_copysignf(float x, float y);

float	x	floating point value to use as the magnitude.
float	y	floating point value to use as the sign.

(float) Returns the floating point value with the sign of y and the magnitude of x.

The definition of copysign is that copysign(x, y) = abs(x) * sign(y).

Domain: -INF <= x <= INF, -INF <= y <= f

Range: -INF <= z <= INF

This function operates on single-precision floating point values, use SDL_copysign for double-precision floats.

It is safe to call this function from any thread.

This function is available since SDL 3.1.3.
