Add

 

 

Overview

The + function returns the sum of its arguments. If no arguments are specified, + returns zero.

Complex

The + function adds a variety of numeric data types to a complex number.

Usage

The + function is used whenever it is necessary to compute the sum of a set of Numbers.

Complex

The + function is used to sum numeric data types where at least one of the addends is complex. Will also handle immediate types. Since complex numbers are heap objects, they require more space. Operations on these types are slower than on immediate types.

 

Syntax

Expression:

(+ num ...)

Arguments Name Type Description
Argument:num ... Number Zero or more Numbers

Returns:

Computes the sum of all the Numbers in the argument list. If the argument list is empty, the + function returns 0.


Expression:

(+ N1 N2 ...)

Arguments Name Type Description
Argument:N1 N2 ... Number A numeric type.

Returns:

A complex number holding the sum of N1, N2, N3, etc.
