<h2>Syntax</h2>
<dl>
<dt>(sin <i>expr</i>)</dt>
<dd><i>expr</i> - floating point number or expression<br>
returns - the sine of the number</dd>
</dl>
<h2>Description</h2>
<p>The 'sin' function returns the sine of the 'expr'. The 'expr' is in
radians.</p>
<h2>Examples</h2>
<pre class="example">
(sin 0.0) <font color="#008844">; returns 0</font>
(sin .5) <font color="#008844">; returns 0.479426</font>
(sin 1.0) <font color="#008844">; returns 0.841471</font>
(sin (/ 3.14159 2)) <font color="#008844">; returns 1</font>
(sin 3.14159) <font color="#008844">; returns 2.65359e-06</font>
(sin 0) <font color="#008844">; error: bad integer operation</font>
(sin 1.) <font color="#008844">; error: bad integer operation</font>
</pre>
<p><b>Common Lisp:</b> Common LISP allows for integer numbers, which
XLISP does not support for 'sin'.</p>
<p>See the
<a href="../manual/xlisp-man-023.htm#sin">sin</a>
function in the <nobr>XLISP 2.0</nobr> manual.</p>
