Hey.. I'm stuck.. I'm a little rusty with my VB.. And I have a review program.. I need to do some Mod-type function..

I have two numbers let's say.. 6.43 and 6.57... When I divide by 1 (using "\" instead of "/").. I get 6 for the first and 7 for the second.. I need to get 6 for both of them because I am using it's remainder to divide again.. It's a change dispensing loop by the way.... First 1's, then .25's, then .10's etc.. How do I get the Mod function to round down?
