Greg, just wanted you to know.

I read up the manual (after trying your suggestion) and it turns out
that the modulo divisor (%) converts to integer before doing the
division. I'm not sure why it didn't work for me and apparently worked
for you.

However, I then changed the test to

if ($var > (int) $var)

and that did the trick.

So thanks for getting me on the right track.
