Syntax

The syntax for - calls is:

-(params)

@-(params)

Description

- is the arithmetic operator for subtraction, it takes $n\ne 0$ input parameters $p_1,\dots ,p_n$ that should all be numbers and returns $p_1-\dots -p_n$ performed from left to right. For example, $-(p_1,p_2,p_3)=p_1-p_2-p_3=(p_1-p_2)-p_3$.

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=15, b=13, c=10)
console(-(a, b))
console(-(a, b, c))

n++ example

Example of - being used with n++:

@:=(int, a=15, b=13, c=10)
@console(@-(a, b))
@console(@-(a, b, c))
