+ <h3 id="builtin_get">ste:get</h3>
+ <p>ste:get will return the content of a variable. The parameter <code>var</code> takes the name of the variable to get. Usefult, if you want to get a variable which name is stored in a variable.</p>
+ <p>
+ Example:<br />
+<code><pre>&lt;ste:get var="$foo" /&gt;</pre></code>
+ This will get the variable with the name that is stored in the variable <code>foo</code>.
+ </p>

<h3 id="builtin_calc">ste:calc</h3>
<p>To perform mathematical calculations, you can use ste:calc. ste:calc calculates the mathematical formula it is wrapped around and returns the result. The formula is in the usual <a href="http://en.wikipedia.org/wiki/Infix_notation">infix-notation [ext. Link]</a> and has these operators: <code>+</code>, <code>-</code>, <code>*</code>, <code>/</code> and <code>^</code>. Numbers are always decimal, the decimal mark is <code>.</code> and numbers can be prefixed with an <code>-</code> to indicate a negative number. It is a good idea to wrap a negative number in brackets to prevent wrong evaluation (because <code>-</code> is also an operator). Calculations can be grouped with brackets: <code>(</code> and <code>)</code>.</p>
<p>Real numbers are supported, complex numbers not.</p>
