SDL_copysign3
Copy the sign of one floating-point value to another.
Usage
#include "SDL3/SDL.h"
double SDL_copysign(double x, double y);
Header file
Defined in SDL3/SDL_stdinc.h
Overview
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.
