Aggregate functionsAggregate functions perform statistical analysis on numbers (and also dates or times for some functions) in:
• related fields whether displayed in a portal or not.For example, you can use the Sum function to add the values listed in a portal, as an alternative to creating a report with grouped data and subtotals.The parameter values can include a numeric constant (for example, 10) or any valid expression. A constant parameter in a formula for a repeating field affects the result for every repetition.When repeating field parameters (field1; field2;...) include a non-repeating field, that value is used in the result for only the first repetition unless you use the Extend function.Values in repetitions that exceed the number of repetitions in the calculated field are ignored. For example, a calculated field with three repetitions holds only three results, even when one field referenced in the calculation has five repetitions.
The standard deviation of a population represented by a series of valid non-blank values in a field or fields.
