<h1>JS Math Methods</h1>
<hr />
<h3>JavaScript Math</h3>
<p>
The <strong>JavaScript math</strong> object provides several
constants and methods to perform mathematical operation. Unlike date
object, it doesn't have constructors.
</p>
<h3>JavaScript Math Methods</h3>
<p>Let's see the list of JavaScript Math methods with description.</p>
<table class="table table-striped table-bordered">
<tbody>
