Comparing very small numbers

I have a code where I have to compare between very small numbers. I have a function where I input two values and it gives me the result, which I have to compare with 0. Generally the results are very small, and hence I am not getting accurate results. Any help in this plzz??

What are you seeing, and what would you consider to be "accurate results" for your situation? Also, how small is "very small" ?

Look into using eps() for this.
