point numbers.  It's a design limitation of PCs in 
general.

representation in PCs as a problem:

<FONT face=Arial

floating point numbers plus some optimisation to significantly minimise the 
problems.

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.
