## 3.179. __nv_hypotf

Prototype:

float @__nv_hypotf(float %x, float %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 $\sqrt{{x}^{2}+{y}^{2}}$ . If the correct value would overflow, returns $+\infty$ . If the correct value would underflow, returns 0. If one of the input arguments is 0, returns the other argument
