Currency decimal places

I have a VB6 front end and Access 97 backend project where the customer insists on searching for a dollar amount and applying a percentage increase or decrease.  If we start out with $20.00 and apply 10% increases all is well but as I test the app and apply numbers like 11.11% to $20.00, Access stores 3 ad 4 significant figures to the right of the decimal point in the table.  Then, when the User searched for an amount like $34.47 and the value stored is $34.467, it is never found.  How can I ensure that only two decimal values get stored.  I am using currency with 2 decimal places.

How do you search for an amount? By query? If so, in your query you have to format the amount field to 2 decimal to accomplish this.

Post your query so we can have better understanding.

In your datatable, make sure the field type is
currency (i'm sure it probably already is), and try changing
the decimal places from auto to 2 in the field properties.
also, as chewhoung notes, you may have to change properties
in querries, reports, etc.
 
An alternative might be to add a
rounding statement in the VB code before stuffing the field.

addendum from ssam:  also, set the format in your table to
'fixed.'

I changed the query to include a Format statement "#.00" so only two decimal places gets stored.  The number of decimal places in the field definition within the table affects the display of the data not the way the data is stored.
