Format number to 2 DPs
I have some data that I'm importing and I want to convert to currency format nnn.nn  there doesn't appear to be a way to do this in aperture. Any ideas? I've tried the Round function but no joy  I want to convert 28 to 28.00 etc.

@SpeedySteven I noticed that the reusable formula was exported from a Data Studio 2.4.2 environment. These packages are typically not backwardscompatible, so if you have an earlier version of Data Studio you will probably find that you can't import. Any version 2.4.2 or later should be fine.

Hi @SpeedySteven , there's a good discussion about this problem here: https://community.experianaperture.io/discussion/668/transformtodecimal
The last proposed solution in the thread is probably the most complete.0 
Thanks Henry  that's really helped  I can't seem to save the reusable formula though

Thanks Henry  we need to upgrade

@SpeedySteven This function ought to do what you want, without any need to upgrade anything.
How it works ...
This function takes an input parameter (called inNumber)
Multiply inNumber by 100 and round it to zero decimal places (using HalfEven rounding)
Save the rounded number as a variable "RoundNum"
We're then going to chop this number up into 2 bits  the right two digits (let's call that RightBit) and everything else (LeftBit).
We then concatenate these two bits either side of a decimal point and save it in the variable outString : LeftBit.RightBit
This works for any number except zero, which ends up as ".0", so we have to handle zeroes as a special case, so we check to see if the outString = ".0" and if it does we return "0.00", if not we return outString

I' m trying to use the function but and I'm receiving the following error message.
" 0 isn't a valid scale"
Any ideas to why is it happening?
Many thanks in advance

Hi @Marco_13112001 , I wasn't able to recreate your issue using the function described above. Could you attach an exported dmx of the function you are trying to use, or screenshot it?
Thanks, Henry

@Henry Simms thanks for your reply but after a more thorough research I was able to run it by using the Pad number 2dp function, which gave the same results that I was looking for.
