Are you sure that what you think are numbers are actually numbers, and not
text? If the number is really a number, then a formula doesn't care what
format the number is *displayed* in, but looks at what the stored number is.
If the Conditional formatting hasn't worked, have you tried using the
formula in a helper column and checked the TRUE and FALSE results?
Are you sure that you have inserted the formula I suggested in the "Formula
Is" option under Conditional Formatting? Go back in to "Formula Is" and
check, as Excel will sometimes change what you think you entered.

Uh oh, this does not seem to work; my numbers are either x.5 or x.0; I
need
my x.0's get formatted and all x.5's left as they are. Might the decimal
format be the problem for MOD function?

=MOD(A1,1)=0

Or =MOD(ROUND(A1,1),1)=0 if you want to treat 4.02 as 4.0 in this
respect.

Hello all,

in a conditional formatting scenario, which function do I use to decide
if
the decimal part of the number in a cell is zero (i.e. x.0 and not x.1,
x.2,
...)?
