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

       This function is available since SDL 3.2.0.

       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.

x      floating point value to use as the magnitude.

       y      floating point value to use as the sign.

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

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