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( ± ∞ , y) returns ± ∞ .

Note:
