Function

Concept

Function is the advanced feature in programming and is useful to make scripts more smart. Function can combine a bunch of procedure into one simple command.

Declaration / Arguments / Return

The syntax to define functions is following:

void <function name>(<arguments data type> <arguments name>){...}

Following is the simplest example of function:

Also you can make functions that can return values. Functions of this kind are something like components in Grasshopper. The syntax to define function with return is following:

<data type of return value> <function name>(<arguments data type> <arguments name>){
 ...
 return <value to return>;
}

Following is the example:

Usage

Using function is very easy. Following is a example to use previous function:
