<a name="index-exp10"></a>
<a name="index-exp10f"></a>
<p><strong>Synopsis</strong>
</p><div class="example">
<pre class="example">#include &lt;math.h&gt;
double exp10(double <var>x</var>);
float exp10f(float <var>x</var>);

</pre></div>
<p><strong>Description</strong><br>
<code>exp10</code> and <code>exp10f</code> calculate 10 ^ <var>x</var>, that is, 
10 raised to the power <var>x</var>.
</p>
<br>
<p><strong>Returns</strong><br>
On success, <code>exp10</code> and <code>exp10f</code> return the calculated value.
If the result underflows, the returned value is <code>0</code>.  If the
result overflows, the returned value is <code>HUGE_VAL</code>.  In
either case, <code>errno</code> is set to <code>ERANGE</code>.
</p>
<br>
<p><strong>Portability</strong><br>
<code>exp10</code> and <code>exp10f</code> are GNU extensions.
