Calculate sum of items or function of items (FloatNamedArraylist, NamedArraylist, and UnicodeNamedArraylist classes)

[Introduced in Sirius Mods 7.8]


This method returns by default the sum of the values of the items in the collection, or it returns the sum of the items after a specified function has been applied to them.

Syntax

%number = anyNal:Sum[( [itemFunction])]

Syntax terms

%number A Float variable to contain the numeric result.
anyNal An FloatNamedArraylist, NamedArraylist, or UnicodeNamedArraylist object.
itemFunction A function that operates on the type of the items in the collection. It may be a local method or method variable or a class member (Variable, Property), and it must return an intrinsic (probably Float) value.

The default itemFunction value is the special identity function, This, which simply returns the item value.
