PropertyDefinition :: precision - Precision value
A precision can be defined for numerical, date and time values. For date and time values the precision determines the "to string" conversion of date and time values. For numerical fields the precision defines the number of digits behind the decimal point. Negative precisions allow defining a decimal factor.
The precision is an integer value, which might be 0, negative or positive.
Definition of precision for numbers is an ODABA specific extension. When the member is an aggregation dimension, the precision defines the number of levels for the dimension.
The precision defines the number of decimal positions behind the decimal point for numerical valued. For date and time values it defines the way of presenting the values in character presentations.
