<p>DeskCalc est une calculatrice simple qui a néanmoins quelques fonctionnalités qui ne sont pas visibles au premier regard.</p>
<img src="../../images/apps-images/deskcalc.png" alt="deskcalc.png" />
<ul>
<li><p>DeskCalc understands much more than its simple keypad suggests.<br />
Besides the operators <tt>+</tt>, <tt>-</tt>, <tt>*</tt>, <tt>/</tt>, <tt>%</tt>, <tt>^</tt> and the constants <tt>pi</tt> and <tt>e</tt> the following math functions are supported:<br />
<tt>acos</tt>, <tt>asin</tt>, <tt>atan</tt>, <tt>atan2</tt>, <tt>ceil</tt>, <tt>cos</tt>, <tt>cosh</tt>, <tt>exp</tt>, <tt>floor</tt>, <tt>log</tt>, <tt>log10</tt>, <tt>pow</tt>, <tt>sin</tt>, <tt>sinh</tt>, <tt>sqrt</tt>, <tt>tan</tt>, <tt>tanh</tt>.</p></li>
<li><p>When it comes to user input, DeskCalc is quite tolerant:<br />
<tt>/</tt>, <tt>:</tt>, <tt>\</tt> are all interpreted as division operators,<br />
<tt>*</tt>, <tt>x</tt> are valid symbols for multiplication.<br />
Also, be aware that <tt>.</tt> and <tt>,</tt> are both considered floating points, which means you mustn't use them as 1000 separators.</p></li>
<li><p>Right-clicking offers these options:</p>
<table summary="layout" border="0" cellspacing="0" cellpadding="2">
<tr><td><span class="menu">Enable Num Lock on start up</span></td><td style="width:15px;"></td><td>automatically activates the number block when launching DeskCalc</td></tr>
<tr><td><span class="menu">Show Keypad</span></td><td></td><td>hides the keypad when deactivated</td></tr>
</table></li>
<li><p>You can resize the calculator until it fits your needs and then put it as <a href="../gui.html#replicants">Replicant</a> onto the Desktop via drag&amp;drop of the symbol in the bottom right corner. Make sure <span class="menu">Show Replicants</span> is activated in the Deskbar.</p></li>
<li><p>Le clavier peut être coloré en faisant glisser dessus n'importe quelle source de couleur comme par exemple, à partir de <span class="app">Icon-O-Matic</span>.</p></li>
<li><p>Vous pouvez remonter ou descendre dans l'historique des calculs effectués avec <span class="key"></span> et <span class="key"></span>.</p></li>
<li><p>You can select DeskCalc's contents and drag&amp;drop it into any application. Or you drop it into a Tracker window or onto the Desktop and a text file with that clipping is created there.</p>
<p>Even better, the reverse is also possible:<br />
Create clippings as described at various stages of your calculation and go back to them by drag&amp;dropping them back into DeskCalc.<br />
Or you drag&amp;drop a calculation directly out of an email onto DeskCalc.</p></li>
<li><p>DeskCalc peut être utilisé dans le Terminal. Il suffit de mettre l'expression entre guillemets, comme ceci :</p>
<pre class="terminal">~&gt; DeskCalc "sin(45)*(cos(12)+3.45)"
