Bytecode implementation of the Math Parser.
The bytecode contains the formula converted to revers polish notation stored in a continious memory area. Associated with this data are operator codes, variable pointers, constant values and function pointers. Those are necessary in order to calculate the result. All those data items will be casted to the underlying datatype of the bytecode.
