HYPOT — Euclidean distance function#

HYPOT(X, Y)#

HYPOT(X,Y) is the Euclidean distance function. It is equal to sqrt{X^2 + Y^2}, without undue underflow or overflow.

Parameters
  • X – The type shall be REAL.

  • Y – The type and kind type parameter shall be the same as X.

Returns

The return value has the same type and kind type parameter as X.

Standard:

Fortran 2008 and later

Class:

Elemental function

Syntax:
RESULT = HYPOT(X, Y)
Example:
program test_hypot
  real(4) :: x = 1.e0_4, y = 0.5e0_4
  x = hypot(x,y)
end program test_hypot
