This question already has an answer here:

Generate random number between two numbers in JavaScript

18 answers

I am using this function to generate and alternate random values inside a div

var change_price = $('#myprice');

animationTimer = setInterval(function() {

  change_price.text( ''+   Math.floor(Math.random() * 100) );      

}, 1000);

#myprice {

  padding: 20px;

  font-size:24px;

  color: green;

}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div id="myprice">50</div>

What I want to do is to control the min value too.
For example, to have random generated values from 50 to 100.
Not starting from zero(0) as other posts do

As mentioned in mozilla developer you can generate random number between max and min as shown in bottom

Math.floor(Math.random() * (max - min + 1)) + min;

So your code should changed to

var change_price = $('#myprice');

animationTimer = setInterval(function() {

  change_price.text(Math.floor(Math.random() * (100-50+1)) + 50);

}, 100);

#myprice {

  padding: 20px;

  font-size:24px;

  color: green;

}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div id="myprice">50</div>
