        These binary operators perform arithmetic on vector
        objects.  They return numeric vectors containing the
        result of the element by element operations.  The ele-
        ments of shorter vectors are recycled as necessary.
        The operators are `+' for addition, `-' for subtraction
        `*' for multiplication, `/' for division and `^' for
        exponentiation.  `%%' indicates `x mod y' and `%/%'
        indicates integer division.

        Objects such as arrays or time-series can be operated
        on this way provided they are conformable.
