If you use NUMERIC or DECIMAL fields in a database, they are mapped to TFloatField by default.

If you set EnableBCD option to True, UniDAC uses TBCDField.
If you set EnableBCD option to True, UniDAC uses TFmtBCDField.

TBCDField and TFmtBCDField hold exact values. While TFloatField holds approximate values. So you may enable these options if you need to get exact values for NUMERIC fields.
