3.112. __nv_fdimf

Prototype: 

float @__nv_fdimf(float %x, float %y)

Description:

Compute the positive difference between x and y. The positive difference is x - y when x > y and +0 otherwise.

Returns:

Returns the positive difference between x and y.

  • __nv_fdimf(x, y) returns x - y if x > y.

  • __nv_fdimf(x, y) returns +0 if x ≤ y.
