Trying to round a quotient down
Posted on 2008-11-12
I am dividing two decimals. I need the quotient to always round down.Also, the resulting quotient should be a whole number integer. Currently I can make the quotient round to the nearest whole number (int numoftwenties = (int)Math.Round((decimal)change /20.00m);, but I need it round down. I am trying to calculate the number of twenty dollar bills that would be given back as change to a customer.
For example if a customer was to receive 95.00 dollars in change back. They would receive 4 (not 5)twenty dollar bills back.
