__device__ float remainderf ( float  x,
float  y 
)

Compute single-precision floating-point remainder r of dividing x by y for nonzero y. Thus $ r = x - ny$. The value n is the integer value nearest $ \frac{x}{y} $. In the case when $ | n -\frac{x}{y} | = \frac{1}{2} $, the even n value is chosen.

Returns:

  • remainderf(x, 0) returns NaN.
  • remainderf($\pm \infty$, y) returns NaN.
  • remainderf(x, $\pm \infty$) returns x for finite x.
