Sometimes, we want to compare decimal numbers with JavaScript.

In this article, we’ll look at how to compare decimal numbers with JavaScript.

### How to compare decimal numbers with JavaScript?

To compare decimal numbers with JavaScript, we can round both numbers and then compare them.

For instance, we write:

```
const a = 99.99
const b = 101.99
console.log((Math.round(a * 100) > Math.round(b * 100)))
```

to multiply `a`

and `b`

by 100 and call `Math.round`

with the returned number to get rid of the decimals.

Then we use > to compare them.

Since `a`

is smaller than `b`

, the console log should log `false`

.

### Conclusion

To compare decimal numbers with JavaScript, we can round both numbers and then compare them.
