<h3 class="section">4.3 Single Precision Data Types</h3>
<p>Octave includes support for single precision data types, and most of the
functions in Octave accept single precision values and return single
precision answers. A single precision variable is created with the
<code>single</code> function.
</p>
<a name="XREFsingle"></a><dl>
<dt><a name="index-single"></a>Built-in Function: <em></em> <strong>single</strong> <em>(<var>x</var>)</em></dt>
<dd><p>Convert <var>x</var> to single precision type.
</p>
<p><strong>See also:</strong> <a href="Numeric-Data-Types.html#XREFdouble">double</a>.
</p></dd></dl>
<p>for example:
</p>
<div class="example">
<pre class="example">sngl = single (rand (2, 2))
⇒ sngl =
0.37569 0.92982
0.11962 0.50876
class (sngl)
⇒ single
</pre></div>
<p>Many functions can also return single precision values directly. For
example
</p>
<div class="example">
<pre class="example">ones (2, 2, "single")
zeros (2, 2, "single")
eye (2, 2, "single")
rand (2, 2, "single")
NaN (2, 2, "single")
NA (2, 2, "single")
Inf (2, 2, "single")
</pre></div>
<p>will all return single precision matrices.
