Comparing Code

I've got the old correlation function code (where it creates the randoms inside the code) spitting out the randoms it is using to a file, and I am then comparing the correlation function to my new code using these random files. Here are the two correlation function values:

New code:

5.8750000000 0.4501698754

The numbers are close, but not exactly the same... they should be exactly the same I think. :( I'm looking deeper into the calculation to see where the difference is exactly.
