Not able to use Math.ceil in Javascript

I'm using Onready function in which I'm calling a function say func();

In func() I'm using Math.ceil on a decimal value stored in a variable, but it is not working. But if I use Math.ceil in console on same variable then it is working fine.

How to use it in my function?

    You should assign the Math.ceil(..) returned value to a variable.

    let xyz = 4.6; xyz = Math.ceil(xyz); console.log(xyz);

    Instead of calling your function from onReady, try just directly adding this line of code in your HTML document:

     

    <script> console.log(Math.ceil(-7.004)); </script>

      Hi @shagunmalik 

       

      You can use Math.ceil inside a function like below:

      $(document).ready(function () {
          alert(someName());
      });


      function someName() {
          var x = 0.95;
          return Math.ceil(x);
      }

       

      On page load it will give a value of 1 as alert.

       

      And the below one gives as 5.

       

      $(document).ready(function () {
          alert(someName());
      });


      function someName() {
          var x = 4.6;
          return Math.ceil(x);
      }

       

      Thanks!

          Hi @shagunmalik,

           

          What is the error that you are seeing in the console? Can you please share the log?

           

          Thanks,

            Hi @kiran_vedantam, there is no error, it is that like if I want to round off 4.6 to 5 using Math.ceil then it is not working, It is showing 4.6 only but If I type the same code in console then it is working fine and showing 5.
