<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>Wraps a <a class="el" href="classgeos_1_1noding_1_1Noder.html">Noder</a> and transforms its input into the integer domain. </p>
<p>This is intended for use with Snap-Rounding noders, which typically are only intended to work in the integer domain. Offsets can be provided to increase the number of digits of available precision. </p>
