public final class NumericOp
extends java.lang.Object
```
This class contains static methods to evaluate operations on Numeric operands. If the operands are absolute numerics the result is computed rigth away and a new absolute numeric is return. If one of the operands are relative a n operation node is created with the operation and the operands. The evaluation of the operation can then occur when getNumericValue() is called.
