Sign(A, B)
Sign: INTEGER or REAL function, the exact type being the result of cross-promoting the
types of all the arguments.
A: INTEGER or REAL; scalar; INTENT(IN).
B: INTEGER or REAL; scalar; INTENT(IN).
Intrinsic groups: (standard FORTRAN 77).
Description:
Returns `ABS(A)*s', where s is +1 if `B.GE.0', -1 otherwise.
See Abs Intrinsic, for the function that returns the magnitude of a value.
