Subject: Re: Match part of the calculated value

Hi,
   Actually if you see my gross1 and gross2 values, the differences are 
only at decimal level.
the first 3 numbers are in most cases matching.
So maybe i should go for 3 number/character match depending whether i am 
retrieving it as a number or a string.

gross1 = 567.45 * 10
gross2 = 567.88 * 10

Thanks
