The keyword parameters <em>accuracy=a</em> and <em>iterations=i</em>,
where <em>a</em>and <em>i</em> must be positive integer numbers, control the
iterative algorithms: the iteration is continued until
the local error is below 10**-a; if that is impossible
within <em>i</em> steps, the iteration is terminated with an
error message. The values reached so far are then returned
as the result.
