NAME

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

HEADER FILE

Defined in SDL3/SDL_stdinc.h

SYNOPSIS

#include "SDL3/SDL.h"

double SDL_copysign(double x, double y);

DESCRIPTION

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 double-precision floating point values, use

SDL_copysignf
for single-precision floats.

FUNCTION PARAMETERS

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

RETURN VALUE

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

THREAD SAFETY

It is safe to call this function from any thread.

AVAILABILITY

This function is available since SDL 3.2.0.
