<h2>Integer part</h2>
<p>In mathematics, the <strong>floor</strong> (also known as the <em>integer part</em>) of a number <em>n</em> is the biggest integer number that is smaller than <em>n</em>.</p>
<p>The <strong>ceiling</strong> of a number <em>n</em> is the smallest integer number that is greater than <em>n</em>.</p>
<br />
<h3>Notation:</h3>
<p>The floor (integer part) of a number <em>n</em>: [n] = &lfloor;n&rfloor;</p>
<p>The ceiling: &lceil;n&rceil;</p>
<br />

<h2>Fractional part</h2>
<p>In mathematics, any real number can be written as <em>n</em> + <em>r</em>, where <em>n</em> is an integer, and <em>r</em> (the fractional part) is a nonnegative real number smaller than 1.</p>
<p>The fractional part of a number <em>n</em> can be written as the difference between <em>n</em> and its integer part (floor):</p>
