Method Detail

### run

    public void run(java.util.Stack<java.lang.Object> stack)
             throws EvaluationException

  Calculates the result of applying the "+" operator to the arguments from the stack and pushes it back on the stack.

  Specified by:
    `run` in interface `PostfixMathCommandI`
  Throws:
    `EvaluationException`

### add

    public java.lang.Object add(java.lang.Object param1,
                                java.lang.Object param2)
                         throws EvaluationException

  Adds two numbers together. The parameters can be of type Number, Complex, or String. If a certain combination of types is not supported, a EvaluationException is thrown.

  Parameters:
    `param1` - The first parameter to be added.
    `param2` - The second parameter to be added.
  Returns:
    The sum of param1 and param2, or concatenation of the two if they are Strings.
  Throws:
    `EvaluationException`

### add

    public java.lang.Double add(java.lang.Number d1,
                                java.lang.Number d2)
