Description

Name: rmT116609			Date: 11/18/2002


DESCRIPTION OF THE PROBLEM :
There is no function Math.sign() for finding the sign of its argument
positive => +1, negative => -1, zero => 0

CUSTOMER WORKAROUND :
This function is not strictly needed, but it can sometimes be more useful than lots of if then else clauses.
