The SUM function returns a value that is the sum of the arguments.
The function type depends on the argument types, as follows:
| Argument Type | Function Type |
|---|---|
| All arguments integer | Integer |
| Numeric (some arguments can be integer) | Numeric |
Format .------------. V | >>-FUNCTION SUM--(----argument-1-+--)--------------------------><
The returned value is the sum of the arguments. If the argument-1 series are all integers, the value returned is an integer. If the argument-1 series are not all integers, a numeric value is returned.
(argument-1)
(argument-11 + argument-12)
(argument-11 + argument-12 + ... + argument-1n)
