  66 <p>DeskCalc is a simple calculator that nevertheless has some nice features that aren't apparent on first sight.</p>
  67 <img src="../images/apps-images/deskcalc.png" alt="deskcalc.png" />
  68 <ul>
  69 <li><p>DeskCalc understands much more than its simple keypad suggests.<br />
  70 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 />
  71 <tt>!</tt>, <tt>acos</tt>, <tt>asin</tt>, <tt>atan</tt>, <tt>atan2</tt>, <tt>cbrt</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>
  72
  73 <li><p>Right-clicking offers these options:</p>
  74 <table summary="layout" border="0" cellspacing="0" cellpadding="2">
  75 <tr><td colspan="2"><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>
  76 <tr><td colspan="2"><span class="menu">Radiants/Degrees</span></td><td></td><td>Switch between "rad" and "deg" as unit for angular measure.</td></tr>
  77 <tr><td><span class="menu">Compact</span></td><td><span class="key">ALT</span> <span class="key">0</span></td><td></td><td>A minimal view mode that hides the keypad.</td></tr>
  78 <tr><td><span class="menu">Basic</span></td><td><span class="key">ALT</span> <span class="key">1</span></td><td></td><td>The standard look of DeskCalc.</td></tr>
  79 <tr><td><span class="menu">Scientific</span></td><td><span class="key">ALT</span> <span class="key">2</span></td><td></td><td>Show additional buttons for advanced calculations.</td></tr>
  80 </table></li>
  81 <li><p>When it comes to user input, DeskCalc is quite tolerant:<br />
  82 <tt>/</tt>, <tt>:</tt>, <tt>\</tt> are all interpreted as division operators,<br />
  83 <tt>*</tt>, <tt>x</tt> are valid symbols for multiplication.<br />
  84 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>
  85 <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>
  86 <li><p>The keypad can be colored with a drag &amp; drop from any color well, e.g. from <span class="app">Icon-O-Matic</span>.</p></li>
  87 <li><p>You can move up and down in a history of past calculations with <span class="key">↑</span> and <span class="key">↓</span>.</p></li>
  88 <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>
  89 <p>Even better, the reverse is also possible:<br />
  90 Create clippings as described at various stages of your calculation and go back to them by drag &amp; dropping them back into DeskCalc.<br />
  91 Or you drag &amp; drop a calculation directly out of an email onto DeskCalc.</p></li>
  92 <li><p>DeskCalc can be used in Terminal. Just put the expression in double quotes, like this:</p>
  93 <pre class="terminal">~&gt; DeskCalc "sin(45)*(cos(12)+3.45)"
  94 3.65365546732025461817951947270058</pre>
  95 <p>Note: Used in the Terminal, DeskCalc will always use radians as unit for these trigonometric functions.</p></li>
