3.193. __nv_hypotf

float @__nv_hypotf(float %x, float %y)

Calculate the square root of the sum of squares of two arguments.

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

Note

For accuracy information, see the CUDA C++ Programming Guide, Mathematical Functions Appendix, Single-Precision Floating-Point Functions section.

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
