I have a formula in Cell H14 to calculate a value 
=SQRT((H11-$C11)^2+(H12-$C12)^2)*2
Then I have a conditional format for the same cell (H14).
The conditional format is "If cell value is >H13" format the font red.

The conditional format appears to work. Except for when the numbers are equal. I'm guessing it's because it really isn't equal. I have went out 30 decimal places and it shows all zeros. I have tried "TRUNC" and "ROUND" with no luck. Any ideas/suggestions?

I also have another similar problem with this formula 
=IF(H14<=G13,"X","")
It works, except when the values are equal (or appear to be).

Thanks very much for your time and help!
