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
