Lucas,

Your GPS is putting out floating point data?

If you really need a floating point comparison, you'll first need to find out what floating point format the data is stored in.  If it's IEEE-754, then you're ahead of the game.  Check out this page:

In particular, look down the page under the heading [b]Comparing using integers[/b].  This describes a features of IEEE-754 floats which says that if you're just doing a comparison, you can treat the data as 32 bit integers and then simply compare tham.  For this you'll need to find out the value of .02 as an IEEE-754 format float, and then do a 32 bit integer compare of it to your incoming data.  

Thanks,
