# Rounding a number to 2 decimal places only if there are decimal places Posted on: 2012-05-30

I couldn’t find it done this way anywhere else, so I thought I’d share:

```
var number = 3.14159;
// If there are decimal places
if ( number % 1 !== 0 ) {
// Cast to string and return the last two numbers.
number = number.toFixed(2);
}
// number is now '3.14'
```

If you really wanted to have a one liner, you could use a ternary operator and rely on the fact that 0 is falsy:

`number = (number % 1) ? number.toFixed(2) : number;`

Nice and easy!
