DESCRIPTION
SQRT(X) computes the square root of X.

STANDARD
Fortran 77 and later

CLASS
Elemental function

SYNTAX
RESULT = SQRT(X)

ARGUMENTS

X The type shall be REAL or COMPLEX.

The return value is of type REAL or COMPLEX. The kind type parameter is the same as X.

EXAMPLE
          program test_sqrt
            real(8) :: x = 2.0_8
            complex :: z = (1.0, 2.0)
            x = sqrt(x)
            z = sqrt(z)
          end program test_sqrt
