<h1 style="text-align: center;">&nbsp;Math Object</h1>
<h2>[WHAT]</h2>
<ol>
<li>[] the Math object is used to perform a number of mathematical functions.</li>
</ol>
<h2>[WHY]</h2>
<ol>
<li>[] to perform standard math operations on numbers without having to write&nbsp;</li>
</ol>
<h2>[WHERE]</h2>
<ol>
<li>[] you need to perform 'standard' mathematical functions on a given number, such as sqrt, log, sin,</li>
</ol>
<h2>[WHEN]</h2>
<ol>
<li>[]&nbsp;</li>
</ol>
<h2>[EXAMPLE]</h2>
<ol>
<li><strong>[] generating a random number<br /></strong></li>
</ol>
<div>var randomNum = Math.random() // returns a value between 0 and 1</div>
<div><ol>
<li><strong>[] generating a random number between 1 and 100</strong><strong></strong><br /><strong></strong></li>
</ol>
<div>
<div>getRandomBetween(min,max){</div>
<div>&nbsp;&nbsp; return Math.random() * (max - min) + min;</div>
<div>}</div>
<div>console.log(getRandomNumberBetween(1,100); // this returns a float, so will get 51.78</div>
<div><ol>
<li><strong>[] would you then use Math.round() or Math.floor to return an integer value ?</strong></li>
</ol>round would return 52, floor would return 51</div>
</div>
</div>
<ol>
<li><strong>[] get the largest number in a given set of numbers<br /></strong></li>
</ol>
<div>var largest = Math.max(17,9,23,44);</div>
<h2>[HOW-TO]</h2>
<ol>
<li>[]</li>
</ol>
