A string doesn't equal itself

Um, yes, that was the point :) I think Rev handles up to 20 digits of 
precision after the decimal point. So as the 1 and 2 are beyond its 
precision, it considers the two (numeric) values equal. As numbers, they are 
"equal"; as strings they are not.

FYI, Excel only gives you 14 digits of precision, so it would think

3.14159265358972222222 = 3.141592653589791111111 is "true."

Please no Microsoft jabs, I'm just trying to illustrate the #1 number 
cruncher out there is not immune from these issues.
