## Class NumericOp

- java.lang.Object
- - org.apache.fop.fo.expr.NumericOp

-     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.
