## Expression port

A advanced math expression evaluator is used by some of the nodes. Normal math syntax is used that is +, -, *, / and ^. Variables can also be defined to help organize the expression. Multiple statements can be written on the same line by using the ; character as sperator

### Examples

```
(x * x) + (y * y)
x ^ 2 + y ^ 2
sqrt((x * x) + (y * y))
x = r * cos(d); y = r * sin(d)
```
