To configure <span class="application">Genius Mathematics Tool</span>, choose
<span class="guimenu">Settings</span> → <span class="guimenuitem">Preferences</span>.
There are several basic parameters provided by the calculator in addition
to the ones provided by the standard library. These control how the
calculator behaves.
</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Changing Settings with GEL</h3><p>
Many of the settings in Genius are simply global variables, and can
be evaluated and assigned to in the same way as normal variables. See
<a class="xref" href="ch05s02.html" title="Using Variables">the section called “Using Variables”</a> about evaluating and assigning
to variables, and <a class="xref" href="ch11s03.html" title="Parameters">the section called “Parameters”</a> for
a list of settings that can be modified in this way.
</p><p>
As an example, you can set the maximum number of digits in a result to 12 by typing:
</p><pre class="programlisting">MaxDigits = 12
</pre><p>

If unchecked,
either the default or any previously saved settings are used each time Genius starts
up. Note that
settings are saved at the end of the session, so if you wish to change the defaults
check this box, restart <span class="application">Genius Mathematics Tool</span> and then uncheck it again.

(<a class="link" href="ch11s03.html#gel-function-MaxErrors"><code class="function">MaxErrors</code></a>). If you set this to 0 then
all errors are always returned. Usually if some loop causes
many errors, then it is unlikely that you will be able to make
sense out of more than a few of these, so seeing a long list
of errors is usually not helpful.

In addition to these preferences, there are some preferences that can
only be changed by setting them in the workspace console. For others
that may affect the output see <a class="xref" href="ch11s03.html" title="Parameters">the section called “Parameters”</a>.
