```
    Description copied from class: Calculator
    
    Perform an arithmetic operation
    
    Specified by:
    
    compute in class Calculator
    
    Parameters:
    
    a - the first operand. Must not be null, and must be an instance of the type implied by the class name.
    
    b - the second operand. Must not be null, and must be an instance of the type implied by the class name.
    
    c - the XPath dynamic evaluation context
    
    Returns:
    
    the result of the computation, as a value of the correct primitive type
    
    Throws:
    
    XPathException - in the event of an arithmetic error
  - getResultType
