    Relative and absolute error

    An approximation
    x*is accurate to precisely 6 decimal places. Does this correspond to an absolute or relative error, and what is its maximum magnitude?

    (c) An approximation x*is accurate to precisely 6 significant figures. Does this correspond to an absolute or relative error, and what is its maximum magnitude?



    I know Absolute error of approximation x* to a real number x is given by |x-x*| and relative error is given by |x-x^*|/|x|.

    I am not sure how to use the above to solve the question.

    thanks for any help.

    Does "six decimal places" change to "five decimal places" if you use bigger numbers?
