`HYPOT`

— Euclidean distance function*Description*:`HYPOT(X,Y)`

is the Euclidean distance function. It is equal to*\sqrt{X^2 + Y^2}*, without undue underflow or overflow.*Standard*:Fortran 2008 and later

*Class*:Elemental function

*Syntax*:`RESULT = HYPOT(X, Y)`

*Arguments*:`X`The type shall be `REAL`

.`Y`The type and kind type parameter shall be the same as `X`.*Return value*:The return value has the same type and kind type parameter as

`X`.*Example*:program test_hypot real(4) :: x = 1.e0_4, y = 0.5e0_4 x = hypot(x,y) end program test_hypot
