Averagebeforereadingbasicsyntaxcrystalsyntax

Returns the average value of a field or an array.
You can also provide a field to group the values of the field (fld).

Average( fld )
Average( fld, condFld )
Average( fld, condFld, cond )
Average( array )

fld	The name of a field whose values should be used to calculate the average value.
condFld	The name of the field that groups the values of fld (if fld isn't an array).
cond	A string declaring the type of grouping to be used on condFld. This only makes sense for groups based on Date, DateTime, Time, and Boolean fields. See Summary Field Conditions for a list of strings you can use here.
array	The name of an array variable whose values should be used to calculate the average value.

A number.

//computes the average of the values of a field "production" of table "factory"
average({factory.production})

//computes the average of the array values
average([1,2,3,4,5,6])	//returns 3.5

//computes the average of the return value (an array) of the formula field "makeArray"
average({@makeArray})

//computes the average of the sales amount of all vendors grouped by vendor
average({Sales.Sale_Amount},{Vendors.VendorID})

If the values in fld should be grouped, a group based on condFld is needed. If the group does not exist in the report, you can add it using i-net Designer or using API method: Engine.addGroup.
