I am confused by this @George. I want to do a division calculation and round the result to 2 decimal places but end up with a number that I can then use in other calculations.

According to Wappler, the Format Number function will leave me with a string which potentially has a delimiter too.

How can I do a round to 2 decimal places and end up with a number? Do I then have to do a `.toNumber()`

on the result? Or is there a `.round(2)`

function somewhere that I can use?

Second Question…

I have just tried to do the above using the experimental mode user interface and I have ended up with this syntax:

```
{{$_SESSION.s_amount_to_pay / s_exchange_rate.formatNumber(2, ".", ",".toNumber())}}
```

Which I am sure is not what I need. I am looking to calculate:

```
s_amount_to_pay / s_exchange_rate
```

Rounded to 2 decimal places.

How do I create that equation on the server side?

Best wishes,

Antony.
