Hi!

You are right for pst-soroban.
Here is the beginning of pgf-soroban where there is computation of new
lengths with decimals in the \ladj command (lengthadjust):
the argument of \ladj is a decimal asking for a drawing a
fraction/multiple of the normal (unit??) one, which draws a soroban of
the actual size.
(I think what you need is decimal lengths??)

Hope this helps.
