Complex Algorithm returning NaN

[MrsMcGuyver]

I have a fairly complex algorithm returning one of 3 different variables. When the pieces of my equation result in a very tiny number (so tiny it's technically negative for the purposes of my program) I get NaN for a result. I've tried to capture the number & turn it back to 0 to prevent the NaN but I it still translates the NaN. Any help/ideas on what else to try?

Interesting.. that must be an incredibly small number... Can you check the result as a string like so:

if ($result eq "NaN&quot {$result=0;}

just a thought..

Matt.

Thanks. I was so wrapped up in the fact that I should have a number the lightbulb didn't go off at a string eq.
