__device__ double fdim ( double  x,
double  y 
)

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.
  • fdim(x, y) returns x - y if x > y.
  • fdim(x, y) returns +0 if x $\le$ y.
Note:
