Subject: Re: Match part of the calculated value

Using the =~ operator on an Integer makes no sense, because the operator 
isn't really defined for Integers. It uses the dummy definition of 
Object#=~, which simply returns nil and does nothing else.

But even if you convert the Integer to a String, it will get you 
nowhere, because that's just not how regular expressions work. You'll 
probably have to convert Gross1 to a String and go through each digit 
(each_char), checking if Gross2 has the same digit (the decimal point 
has to be skipped).

However, I'm not even sure how you want to compare the values:

gross1 = 414.23
gross2 = 542.14

How many matches do we have? 2? 3? Or more?

Please note: Don't use capitalized names. Ruby interprets them as 
constants (which is probably not what you want).
