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.
