<span id="Single-Precision-Data-Types-1"></span><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>
<span id="XREFsingle"></span><dl class="def">
<dt id="index-single"><span class="category">: </span><span><em></em> <strong>single</strong> <em>(<var>x</var>)</em><a href='#index-single' class='copiable-anchor'> &para;</a></span></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))
     &rArr; sngl =
        0.37569   0.92982
        0.11962   0.50876
class (sngl)
    &rArr; 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, &quot;single&quot;)
zeros (2, 2, &quot;single&quot;)
eye (2, 2,  &quot;single&quot;)
rand (2, 2, &quot;single&quot;)
NaN (2, 2, &quot;single&quot;)
NA (2, 2, &quot;single&quot;)
Inf (2, 2, &quot;single&quot;)
</pre></div>

<p>will all return single precision matrices.
</p>
</div>
