## 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
