Description
Specifies the number of digits of accuracy used to store the field value.
Precision can be a value from 0 through 32. However, because TBCDField uses the currency type to work with data from BCD fields, TBCDField limits the precision of the BCD values it can support to 4 decimal places and 20 significant digits. The underlying database table may include values that require greater precision, and setting precision to a value greater than 20 allows you to create a table with higher precision.
