<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.
<!-- ov-flt-re-mat.cc -->
<p><a name="doc_002dsingle"></a>
<div class="defun">
— Built-in Function: <b>single</b> (<var>x</var>)<var><a name="index-single-234"></a></var><br>
<blockquote><p>Convert <var>x</var> to single precision type.
<!-- Texinfo @sp should work but in practice produces ugly results for HTML. -->
<!-- A simple blank line produces the correct behavior. -->
<!-- @sp 1 -->
<p class="noindent"><strong>See also:</strong> <a href="doc_002ddouble.html#doc_002ddouble">double</a>.
</p></blockquote></div>
<p>for example
<pre class="example"> sngl = single (rand (2, 2))
⇒ sngl =
0.37569 0.92982
0.11962 0.50876
class (sngl)
⇒ single
</pre>
<p>Many functions can also return single precision values directly. For
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>
<p class="noindent">will all return single precision matrices.
