<p>Math::BigInt::FastCalc - Math::BigInt::Calc with some XS for more speed</p>
<p>
</p>
<hr />
<h1><a name="synopsis">SYNOPSIS</a></h1>
<p>Provides support for big integer calculations. Not intended to be used by
other modules. Other modules which sport the same functions can also be used
to support Math::BigInt, like <a href="../../../Math/BigInt/GMP.html">the Math::BigInt::GMP manpage</a> or <a href="../../../Math/BigInt/Pari.html">the Math::BigInt::Pari manpage</a>.</p>
<p>
</p>
<hr />
<h1><a name="description">DESCRIPTION</a></h1>
<p>In order to allow for multiple big integer libraries, Math::BigInt was
rewritten to use library modules for core math routines. Any module which
follows the same API as this can be used instead by using the following:</p>
<pre>
<span class="keyword">use</span> <span class="variable">Math::BigInt</span> <span class="string">lib</span> <span class="operator">=></span> <span class="string">'libname'</span><span class="operator">;</span>
</pre>
<p>'libname' is either the long name ('Math::BigInt::Pari'), or only the short
version like 'Pari'. To use this library:</p>
<pre>
<span class="keyword">use</span> <span class="variable">Math::BigInt</span> <span class="string">lib</span> <span class="operator">=></span> <span class="string">'FastCalc'</span><span class="operator">;</span>
</pre>
<p>Note that from <a href="../../../lib/Math/BigInt.html">the Math::BigInt manpage</a> v1.76 onwards, FastCalc will be loaded
automatically, if possible.</p>
<p>
</p>
<hr />
<h1><a name="storage">STORAGE</a></h1>
<p>FastCalc works exactly like Calc, in stores the numbers in decimal form,
chopped into parts.</p>
<p>
</p>
<hr />
<h1><a name="methods">METHODS</a></h1>
<p>The following functions are now implemented in FastCalc.xs:</p>
<pre>
_is_odd _is_even _is_one _is_zero
_is_two _is_ten
_zero _one _two _ten
_acmp _len _num
_inc _dec
__strip_zeros _copy</pre>

<h1><a name="authors">AUTHORS</a></h1>
<p>Original math code by Mark Biggar, rewritten by Tels <a href="http://bloodgate.com/">http://bloodgate.com/</a>
in late 2000.
Seperated from BigInt and shaped API with the help of John Peacock.
Fixed, sped-up and enhanced by Tels <a href="http://bloodgate.com">http://bloodgate.com</a> 2001-2003.
Further streamlining (api_version 1 etc) by Tels 2004-2005.</p>
