How to round to the next largest number?

Solution 1:

You can use the Math.ceil() function.

Math.ceil(1.1) // returns 2

Conversely, if you wanted to round down you'd use Math.floor()

Math.floor(1.8) // returns 1

Here's a demo:

console.table([1, 1.25, 1.49, 1.5, 1.75, 2].map(n => ({
  n,
  "Math.floor(n)": Math.floor(n),
  "Math.ceil(n)": Math.ceil(n),
  "Math.round(n)": Math.round(n),
})));

<script src="https://gh-canon.github.io/stack-snippet-console/console.min.js"></script><script>console.config({maximize:true,timeStamps:false})</script><style>.as-console-wrapper{display:block;}</style>

_{Note: Floor and ceiling functions aren't exclusive to javascript. See this wikipedia entry for more info.}

Solution 2:

Use Math.ceil():

Math.ceil(1.2); // 2

Solution 3:

It does exactly what you want.
