Prototype:

double @__nv_hypot(double %x, double %y) 

Description:

Calculate the length of the hypotenuse of a right triangle whose two sides have lengths x and y without undue overflow or underflow.

Returns:

Returns the length of the hypotenuse x 2 + y 2 . If the correct value would overflow, returns + . If the correct value would underflow, returns 0. If one of the input arguments is 0, returns the other argument
