Hi,

The SimpleDataSet above receives an float value like 1,123456789

SimpleDataSet.FieldByName('ValorCotacao').AsFloat := AdvEdit.AsFloat;

By a break point at this line, I can see that the value of the AdvEdit
is fine, but the number passed to the SimpleDataSet was rouded to
1,123500000. The same situation under MS-SQL don´t get the value rouded.

All TField´s objects are created at run-time, I don´t have any field
on the Fields Editor.

It happens with a set of ClientDataSet / DataSetProvider / SQLDataSet
too.

It also was tested with Interbase and UIB drivers.

Best Regards.
