Does anyone knows if MS 9 uses double precision?

It's due to MetaStock's use of single precision floating point numbers. It's a design limitation of PCs in general.
Even Microsoft acknowledge floating point number representation in PCs as a problem:

although Microsoft seem to have used double precision floating point numbers plus some optimisation to significantly minimise the problems.
Basically, for large numbers you can assume that the final few digits will be inaccurate with MetaStock. Single precision is accurate to around 7 significant digits. Perhaps one day Equis will use double precision floating point numbers.
