```
public enum MathOperator
extends Enum<MathOperator>
```
Mathematical operators used in the math operation. Behaviour of each operator on the stack is described using notation (before -- after), where "before" represents the stack before execution of the operator and "after" represent the stack after execution.
The top of the stack is at the right, e.g. in (x1 x2 -- x1-x2), x2 is the element on the top, x1 is the second from the top and (x1-x2) is the top of the frame after the execution.
