3.111. __nv_fdim

Prototype: 

double @__nv_fdim(double %x, double %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_fdim(x, y) returns x - y if x > y.

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