[olug] Doing math in /bin/bash

I'm trying to do a calculation in a bash script.  Looked at dc, but looks more complicated than it's worth.  Then tried gcalctool.  I get exactly what I want except for one thing, I just need the "whole" number part.  I.e., (a/b)*c mod 1.

declare -i COUNT
COUNT=`gcalctool -s $A*$C/$B`

Was hoping it could be that easy. :-)

Any nifty ideas?
