I am getting a variable “total_point_balance” and i would like to multiply it by an integer:
{{ $(‘Split In Batches’).item.json[“total_point_balance”] x “5” }}
I tried the above but i am getting invalid syntax:
Are simple calculations possible in n8n?
Hi @fxholl 
Sure is possible - all you’d need to do is replace the x in your equation with *. Like so:
great!
I have a follow-up question about formating the resulting number.
In your example, {{ $json.number * 6 }} is 30 . I need the number to be “30,00”. I normally append .toFloat().toFixed(2).replace(“.”,“,”), but I am unsure where to append this
No problem, @fxholl - you could do this like this: {{ $json.number.toString().toFloat().toFixed(2).replace('.',',') }}. If you try to simply use .toFloat(), it’s only callable on a String 
Here is the complete example:
{{ $(‘Split In Batches’).item.json[“total_currency_balance”] *5 }} returns “75”.
But I need “75,00”
I tried {{ $(‘Split In Batches’).item.json[“total_currency_balance”]…toString().toFloat().toFixed(2).replace(‘.’,‘,’) *5 }} but it returns null
Ah, that would be because you’d need to do the calculation before you convert the integer over to a string 
You can then use the rest of the methods I mentioned after multiplying to give you “75,00”, if that makes sense?
