It’s a nice post about rounding.  
But for display you could simply use Number.prototype.toFixed.  
So for example you will do:

```javascript
Math.PI.toFixed(4); // '3.1416'
(8.1234).toFixed(2); // '8.12'
'$' + (2.5).toFixed(2); // '$2.50'

```

I mention display since it returns a string.  
Nice for currency since it will add zeros.

Wow - I had no idea about that function. I’ll revise this article to mention that 😄
