In our old but currently being replace ERP system, some of the files

Fascinating. It's a do-it-yourself floating point field, using two fields.

So if PZQTY = 12345 and PSDCC = 2 it would calculate to:

QtyPer = 12345/(10**2) = 12345/100 = 123.45

However I am getting a result of 123.499.

Are you sure it's not 123.449? Or perhaps 123.4499?

Regardless, no doubt it is subject to the rules Buck was talking about.

In your situation, I would be very tempted to write some kind of UDF
which takes a quantity field and a decimal-places field and returns a
single, accurate, easy-to-work-with number.
