# Rounding a number to 2 decimal places for currency display

A little helper function I wrote to play nicely with cash figures in JavaScript. Pass it any number `v`

and it will return either:

- If
`v`

is one or more cents/pennies/whatever away from a round dollar/pound/whatever: a String that is`v`

rounded to 2 decimal places. - Otherwise:
`v`

as a Number rounded to the nearest dollar/pound/whatever.

So, for example:

The function can therefore return either a Number or a String. I didn’t add a line to convert a return Number to a String because it was completely unnecessary for my purposes, but it would be easy enough by changing line 5 to `integer + "";`

It goes without saying but use as you wish!
