## 3.240. __nv_nextafter

Prototype:

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



Description:

Calculate the next representable double-precision floating-point value following x in the direction of y. For example, if y is greater than x, nextafter() returns the smallest representable number greater than x

Returns:

• __nv_nextafter( $±\infty$ , y) returns $±\infty$ .
