<simpara>
Use the fast-exponentiation method to raise <parameter>x</parameter>
to the power <parameter>y</parameter> with respect to the modulus
<parameter>modulus</parameter>. The optional
<parameter>scale</parameter> can be used to set the number of
digits after the decimal place in the result.
</simpara>
<para>
The following two statements are functionally identical. The
<function>bcpowmod</function> version however, executes in
less time and can accept larger parameters.
<informalexample>
<programlisting role="php">
<![CDATA[
<?php
$a = bcpowmod($x,$y,$mod);
$b = bcmod(bcpow($x,$y),$mod);
/* $a and $b are equal to each other. */
?>
]]>
</programlisting>
</informalexample>
</para>
<para>
<note>
<simpara>
Because this method uses the modulus operation, non-natural numbers
may give unexpected results. A natural number is any positive
non-zero integer.
