There are two policies that effect the iterative algorithms used to implement
|
|
the special functions in this library:

The class <code class="computeroutput"><span class="identifier">max_series_iterations</span></code>
|
|
determines the maximum number of iterations permitted in a series evaluation,
|
|
before the special function gives up and returns the result of <a class="link" href="../error_handling.html#math_toolkit.error_handling.evaluation_error">evaluation_error</a>.

The class <code class="computeroutput"><span class="identifier">max_root_iterations</span></code>
