I'm getting a FALSE when entering this formula.

A2=$789.14
B2=$ 3.14

=(A2-INT(A2))=(B2-INT(B2))

When I evaluate the formula I get notice:

=(.1399999999986)=(B2-INT(B2))

=(.1399999999986)=(.14)

I've know its not a decimal place issue, because I'm entering the amounts myself. I put exactly 789.14.

I also tried =MOD(A2,1)=MOD(B2,1) and it does the same thing.

Spell Check in Excel
Press F7 to start spell check in Excel. Be careful, by default, Excel does not check Capitalized Werds (whoops)
It has to do with the floating point decimal system that Excel uses. A way around it is to use the ROUND function as well... try:

=ROUND((A2-INT(A2)),2)=ROUND((B2-INT(B2)),2)

Hey thanks for your reply.

I googled the "floating point decimal system" (thanks to your reply) and found their is a way to deactivate it.

  1. Click Microsoft Office Button -> Excel Options -> Advanced
  2. Scroll down to "When calculating this workbook" section
  3. Check "Set precision as displayed"
Do see any problems with doing it that way?

If you have any calculations that need to be more accurate, then unticking that option can cause things to go awry.
