<p>The <strong>Factorizator</strong> is an application which displays the <em>factorization</em> of natural numbers. <em>Factorization</em> is defined as the decomposition of the number into prime factors, which multiplied will yeld the original number.</p>
|
|||
|
|
|
|||
|
|
<p>Using the application is very simple, one has to simply type a number in the input text box, and press <em>Calculate</em> (or Enter key). The result is displayed in the <em>Factorization</em> area. The first column shows the original numbers divided by the last divisor, and in the divisor column, the divisors are listed.</p>

<li><strong>Remainder column</strong>: the result of the previous number divided by the divisor.</li>

<h2>Limitations</h2>
|
|||
|
|
<p>The calculator is limited to 128bit floating point numbers (approximate range: <20>1.0 <20> 10<sup>-28</sup> to <20>7.9 <20> 10<sup>28</sup>, or 28-29 digits). However, since factorization can only be done for integer numbers, the numbers that are not integer will be trimmed.</p>
