Review FP tables

[MrSapps]

I think in #1501 we went from not enough to perhaps too much accuracy on FP values. This can be checked by comparing the resulting int value hex with the exe/ida tables.

In the DLL versions its possible to semi automate this checking, once that is done they can be trimmed down to say 4 decimal places to check that they still match. Or indeed that they match with the current level of accuracy.
