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.

Note:

For accuracy information for this function see the CUDA C Programming Guide, Appendix C, Table C-1.

Library Availability:

Compute 2.0: Yes

Compute 3.0: Yes
