Simple Math Function Help in Javascript

This is the webpage --> http://dawasco.unaux.com

I wanted to make a simple math function whereby:

The value x is taken and then added with 0.01 or 1% of x

Basically : x + (0.01x)

Then 1000 is added to the result value i.e.

In this Case : 1.01x +1000

Finally the result is rounded UP to the nearest hundreds

So in this case if we take x=1 then the total ;1001.01 will be rounded up to 1100

1.
Lets say the input value is: 94,000

1% of 94,000 is 940 so:

94,000 + 940 = 94940

94940 + 1000 = 95940

4.
the total i.e. 95940 is rounded Up to the nearest hundreds

95,940 = 96,000

My questions are:
1. How do i set a parameter to round off the values in 100s. math.ceil() here
2. How do i connect the input box and the javascript file
3. How do i display the output in the output box?
4. I tried using variables but failed so basically i need a solution

math.ceil()

If you have been working on this, share your Minimal, Complete, and Verifiable example and explain the problem you are facing in your implementation.

What have you tried so far? Note that the problem, as posted, has a (maybe unexpected) difficulty and could require arbitrary precision floats or similar.

Well i tried using the math.ceil() for rounding up the number i didnt know how to set a parameter which only rounded in 100s

math.ceil()

“i didnt know how to” - newsflash: This is the point were you are supposed to do some basic research! Typing something trivial such as “javascript round number to next 100” into Google would have led you to stackoverflow.com/q/19621455/1427878 in no time.

It should do the trick if you always want to round to the nearest hundred.

function computation(number) {
let newNumber = number + (1/100 * number) + 1000;
let roundedNumber = Math.round(newNumber/100)*100;
return roundedNumber;
}


This is great! But how do I link the <input> and the <output> Tag?

<input>

<output>

Aha you should read the javascript documentation, I can't give you the exact answer, it depend on your HTML and Javascript code :)
