Not able to use Math.ceil in Javascript

[ShagunMalik]

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?

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.

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

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

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!

Thank you.

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>
