NAME

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

SYNOPSIS

       #include <SDL3/SDL_stdinc.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.
