## 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 $r=x-ny$ . 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:

• __nv_remainder(x, 0) returns NaN.

• __nv_remainder( $±\infty$ , y) returns NaN.

• __nv_remainder(x, $±\infty$ ) returns x for finite x.
