Description
Determines the precision used in formatting the value in a floating-point field.
Use Precision to set the maximum number of digits in the string representation (both integer part and fractional part). 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.
