avg(scope, expressionStr)
This computes the arithmetic mean of the value of a expressionStr in a scope. See avg_if() for a for a related conditional operator.
scope describes the notes to be examined and may be any group designator including a find() query.
expressionStr may be any valid expression, but will usually be a reference to an attribute; short form Boolean attribute expressions are acceptable.
For example:
$MyNumber = avg(children(/Catalog),$Price); returns the average price of all the items in Catalog.
