SqRt(X)
SqRt: REAL or COMPLEX function, the exact type being that of argument X.
X: REAL or COMPLEX; scalar; INTENT(IN).
Intrinsic groups: (standard FORTRAN 77).
Description:
Returns the square root of X, which must not be negative.
To calculate and represent the square root of a negative
number, complex arithmetic must be used.
For example, SQRT(COMPLEX(X)).
The inverse of this function is SQRT(X) * SQRT(X).
