[AccessD] Decimal Data Type

I don't use doubles if I can avoid them.  Floating point creep is worse
to debug than spaghetti code, so when I have to calculate those numbers,
I convert them to decimals then save the result back to doubles!

 I run into it when working with other types  of older databases such as
DEC VMS systems  or Progress systems, or MAS90 systems, etc.

 If I can, I try to stick to double and long,  as I hate to do work over
because something  was too small.

 For a challenge, find an old IBM book called  the principles of
operation.  It will explain  many of the older data types from IBM's
point  of view.

Hey Gustav
How does Decimal differ from Double or Currency and do you know why it
was added as a data type?  As Edward has confirmed when Access does the
conversion "you have to hunt through the app and fix things by hand".

That said, Decimal should be avoided as data type in tables as it is
known to be buggy. In VBA, however, it can be quite useful.

Just out of curiosity (because I don't know what it is supposed to be
used for) where would you use it in VBA?

Thanks
