My number has a precision of 2 on the database side. The example I chose
illustrates three guys going to the restaurant and splitting the bill by
three. The bill is $100. I am dividing by 3. Two should pay $33.33 and the
last one $33.34. The calculation I am doing is the following: the first two
will pay $100/3 and the third one the balance which should be $33.34. So, by
default, I use the onFieldChange trigger of the "Debit" field to compute the
amounts:
Credit1.AsCurrency = Debit.AsCurrency / 3;
Credit2.AsCurrency = Debit.AsCurrency / 3;
Credit3.AsCurrency = Debit.AsCurrency - Credit1.AsCurrency -
Credit2.AsCurrency;

This should ensure that Total Debit = Total Credit

Using IBOQuery Alone, I get the correct rounding done to 2 digits. Using the
ClientDatasets Linked to IBObjects, I get the 4 digits problem. It seems
that the DataSetProvider component is reading the size and precision fields
and giving it to the ClientDataSet.

Note that with IBX, this is done correctly.

So, if your number is stored with a precision of two, then to arrive at a
result with a precision of 4 means you must have multiplied or divided by a
number which also had a precision of 2.

So what was your calculation?
