## 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( $±\infty$ , y) returns $±\infty$ .
