  Specified by:
    `run` in interface `PostfixMathCommandI`
  Overrides:
    `run` in class `PostfixMathCommand`
  Throws:
    `ParseException`

### sub

    public java.lang.Object sub(java.lang.Object param1,
                                java.lang.Object param2)
                         throws ParseException

  Throws:
    `ParseException`

### sub

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

### sub

    public Complex sub(Complex c1,
                       Complex c2)

### sub

    public Complex sub(Complex c,
                       java.lang.Number d)

### sub
