<h2>Syntax</h2>
<dl>
<dt>(write-float <i>float</i> [<i>stream</i> [<i>length</i>]])</dt>
<dd><i>float</i> - the floating point number to write<br>
<i>stream</i> - the output stream [default is standard output]<br>
<i>length</i> - the length of the float in bytes [default is 4,
legal values are -4, -8, 4, and 8]<br>
returns - the float</dd>
</dl>
<h2>Description</h2>
<p>The '<nobr>write-float</nobr>' function writes a binary floating point
number to an output stream, created by the
<nobr><a href="open-binary.htm">open-binary</a></nobr> function.</p>
<p><b>Note:</b> Integers and floats are assumed to be
<nobr>big-endian</nobr> [<nobr>high-order</nobr> byte first] and signed,
regardless of the platform. <nobr>To read</nobr> <nobr>little-endian</nobr>
format, use a negative number for the length, e.g. '-4' indicates a
<nobr>4-bytes</nobr>, <nobr>low-order</nobr> byte first. The file should be
opened in binary mode.</p>
