Limit the number of decimal digits in Money Field

Have a look at the BDE control panel, the configuration page, and numeric
formats for decimal places.

Regards,
Greg

Re:Limit the number of decimal digits in Money Field


Hi all!

I'm using Paradox 7 with BDE 5.1.1.

I have a table with a Money field. When a make some processing the value of
this field bacame with 4 decimal digits. But I can't let the field with
these 4 digits. How can I avoid this case?

My processing is a SQL UPDATE that modifies the field (based in some
percentage, because of this the result  may be with 4 decimal digits).
I tried to CAST the value in the UPDATE statement but it didn't work.

Any ideas?

Thanks

Re:Limit the number of decimal digits in Money Field


One problem you may run into, depending on which database format you are
ultimately using, is the numeric-precision problem.  Exactly how many
digits of precision are stored and in what format.

For instance:  MS-Access stores Money as a scaled integer; the value is
multiplied by 10,000 and stored as an integer.  Paradox uses ordinary
floating-point.

try this:
cast(GR_RAP*100 + 0.5 as integer) / 100.0

perhaps it works how do you want
