8.99 SQRT — Square-root function

Description:
SQRT(X) computes the square root of X.
Option:
f95, gnu
Class:
elemental function
Syntax:
X = SQRT(X)
Arguments:

X The type shall be REAL(*) or COMPLEX(*).

Return value:
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
