<p>The <nobr>cl:<b>expt</b></nobr> function computes the result of 'x' to
the power <nobr>of 'y'</nobr>:</p>
<p><div class="box">
<dl>
<dt>(cl:<b>expt</b> <i>base power</i>)</dt>
<dd><i>base</i> - the base<br>
<i>power</i> - the exponent<br>
returns - the result of <i>base</i> to the power of <i>power</i></dd>
</dl>
</div></p>
<pre class="example">
(defun <font color="#0000CC">cl:expt</font> (x y)
(let ((power (expt (float x) y)))
(if (and (integerp x) (integerp y))
(round power)
power)))
</pre>

<p>The <nobr>cl:<b>expt</b></nobr> function accepts integer and floating
point numbers as arguments. <nobr>If both</nobr> arguments are integer
numbers, the result will be an integer number, <nobr>if one</nobr> or both
arguments are <nobr>floating-point</nobr> numbers, the result will be a
<nobr>floating-point</nobr> number. <nobr>In contrast</nobr> to the
Nyquist/XLISP <a href="../../reference/expt.htm">expt</a> function, the
'<nobr>cl:expt</nobr>' function accepts exactly two arguments.</p>
