Syntax

The syntax for + calls is:

f++:  
+(params)

n++:  
@+(params)

Description

+ is the arithmetic operator for addition, it takes a non-zero number of input parameters, if all parameters are numbers it returns their sum, otherwise it returns their string concatenation.

Note: It is typically faster to use exprtk for arithmetic operators, plus the syntax is nicer.

f++ example

Example of + being used with f++:

:=(int, a=10, b=13, c=15)
:=(string, str="hello")
console(+(a, b))
console(+(a, b, c))
console(+(str, ", ", "world!"))

n++ example

Example of + being used with n++:

@:=(int, a=10, b=13, c=15)
@:=(string, str="hello")
@console(@+(a, b))
@console(@+(a, b, c))
@console(@+(str, ", ", "world!"))
