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.
