Well, I've racked my brain on this. For whatever reason, after a number of iterations of comparisions, the statistics code I'm writing for a different project starts comparing inaccurately.

The comparisons I'm doing are for integers, which I solved by doing a cint(integervalue), and for decimal numbers...which I've yet to figure out.

Basic comparisons (a < b) are coming out incorrectly...and I'm a bit at a loss for this. I guess I just don't understand enough as to what's going on with the numbers behind the scenes to figure this out.

Any thoughts?

You may be overflowing a variable. For example, integers only count to 32K approx. Or you may be encountering rounding problems over multiple passes.

Here is a link to VBS datatype info:

Like Doug said, you could be going over your max or having rounding problems. Also check that your numbers aren't null which will give you odd results.

For reference:

Integer(cint) - -32,788 to 32,787
Long (clng) - over 32,787
Double (cdbl) - Anything with decimals (has a high max, but can't remember which)
