jQuery round function

Question

How can I round the number using jQuery?

If the number is 3168 I want to print it as 32. Or if the number is 5233 the result should be 52.

How can I do that? Should I use the Math.round function?

Answer 1

Yes, you should use Math.round (after dividing by 100).

jQuery is a library for DOM traversal, event handling and animation built on top of JavaScript. It doesn't replace JavaScript and doesn't reimplement all its basic functions.

Answer 2

var num = 3168;
$('#myElement').text(Math.round(num/100));

I assume you mean divide by 100, then round? Or did you mean to have decimal places? (In which case, remove the /100 portion)

Also, this is just basic JavaScript. As another user mentioned, jQuery is to work with the document itself, not to perform math operations.

And here is a snippet from the jQuery math library¹:

(function($){
  $.round = Math.round;
})(jQuery);

$.round(3168 / 100) // 32
$.round(5233 / 100) // 52
