Can anyone explaing the reasons for this restriction? Modulo only makes sense when the quotient is an integer. When you divide four inches by three, there isn't anything left over; you have three parts of 4/3 inches each. But if you take three-inch pieces of four inches, you have one inch left over. ~Chris - -- Christopher R. Maden, Principal Consultant, HMM Consulting Int'l, Inc.
