<h1>WriteFloat (filehandle/stream, myFloat)</h1>
<h1>Parameters</h1>
<table>
<tr>
<td>
filehandle/stream = a valid variable set with the OpenFile, WriteFile command,  or OpenTCPStream (v1.52+)
<br />
myFloat = a floating point variable
</td>
</tr>
</table>
<h1>Description</h1>
<table>
<tr>
<td>
Once you've opened a disk file (or stream) for writing, use this command  to write a single floating point number to the file. Note, each value written  uses 4 bytes.

<br />

<br />
Streams can only be used in Blitz Basic v1.52 or greater.
