Division produces NaN

I'm trying to divide the variable number by 100 and get NaN. I'm new to jQuery, can anyone help me to understand what I'm doing wrong?

$.each(data.products, function (i, data) {

    var div_data = "<p>" + data.title + "<br/>" + data.description + "</p>";

    div_data += '<img src="' + data.imageUrl + '" title="Loading..." alt="Loading...">';
    div_data += '<p><a href="' + data.url + '">Buy</a></p>';

    $(div_data).appendTo("#testjson");

    number = '<div class="number">' + data.price + '</div>';
    $('#myElement').text((number / 100));

});

You can do it like this

    number = '<div class="number">' + (data.price/100) + '</div>';
    $('#myElement').text((number ));

This is what you are doing in .text()

('<div class="number">' + (data.price/100) + '</div>')/100

First you're setting number to a string:

number = '<div class="number">'+ data.price + '</div>';

Then you are dividing that string by 100

In JavaScript that results in NaN which is short for Not a Number . This is specified in the spec.

A possible solution could be to divide the number itself by 100, and not the HTML string, for example:

var number = data.price/100;
$('#myElement').text(number);

This would not attach a nested div to your #myElement though.
