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.

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="Verwendung von Variablen">the section called “Verwendung von Variablen”</a> about evaluating and assigning
to variables, and <a class="xref" href="ch11s03.html" title="Parameter">the section called “Parameter”</a> for
a list of settings that can be modified in this way.

As an example, you can set the maximum number of digits in a result to 12 by typing:

many errors, then it is unlikely that you will be able to make
