Firstly, you _really_ want to make your title more accurately reflect the content of the post. At best, you're going to attract bored programmers.
Secondly, you need to make your question more specific. What do you want to compare the values with? What's the actual problem you're trying to solve?
The 'standard' manual for how to ask questions that get useful answers quickly is ESR's How To Ask Questions The Smart Way
I've written a decidedly less thorough but substantially shorter version at http://aviswebsite.co.uk/asking-questions/
I'd rather you read the former, but if you're not going to, at least read the latter, please.
