3.241. __nv_nextafterf

Prototype: 

float @__nv_nextafterf(float %x, float %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_nextafterf( ± ∞ , y) returns ± ∞ .
