Determines the precision used in formatting the value in a floating-point field.

Pascal
property Precision: Integer;
C++
__property int Precision;
Description

Use Precision to set the number of digits beyond the decimal point that the value should be formatted to before rounding begins. Precision affects the format of the floating-point value when it is displayed as a text string, not the actual floating-point value that is stored in the field. 

The default value of Precision is 15 decimal places.

Note: Precision must be greater than or equal to 2. Trying to set Precision to a value less than 2 changes the value of Precision to 2.
