Stephen,

I can't think of a formula that tests whether or not it is a integer however
I can supply another solution:

If A1 = the results of your calculation, let's say 0.5

Then in A2 write =int(A1), this will return the value 1

In A3 write = if(A1=A2,"Yes","No"). This will tell you whether or not your
original value was an integer or not.

You may also wish to check out ROUND (roundup/rounddown) and CEILING formulae.

Regards

Jim
