3.254. __nv_remainder

Prototype:

double @__nv_remainder(double %x, double %y)

Description:

Compute double-precision floating-point remainder r of dividing x by y for nonzero y. Thus $r = x - n y$ . 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:

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

Note:
