Hi there,

I have a survey that utilises a number of calculations to output an answer.
Many of these are basic sums.

My question is whether it is possible to format the numbers for ease of use.
For example I'd like 1000000 to be displayed as 1,000,000 or even 1 000 000

At the moment if I format then it affects the output of the calculation.

Perhaps someone could point me to the correct way to format the fields?

Thanks

Never used (I didn't manage billion of $) but i suppose you are looking forthis kind of expression:
{number_format(123456789)}

Have a look to the "bible" of all expression manager functions

Hi Ben.

Thanks so much for the response we have tried everything but when applying this to the input fields it doesn't work on the "total" field. As in, the result seems to be affected by the inputs.

Is there someway to mask the input field but have the entries sent through only as integers?

Here is the link if you want to see what I'm talking about.

maybe using the EM "round" or "intval" functions
(you may have a look at "ceil" & "floor" as well)

for example using "round" to get a number with 2 decimals:

{round(sum(arg1, arg2),2)}
if arg1=2.1111 & arg2=2.222 the result will be 3.33

I suppose (not tested) the following syntax will return an integer
{round(sum(arg1, arg2),0)}
if arg1=2.1111 & arg2=2.222 the result will be 3

I hope that someone else can give you more accurate help; Maybe using javascript instead EM. :)

Hi Ben, unfortunately that didn't work. The problem is we can apply the formatting but it breaks the calculations. We need some sort of 'mask' that will show the formatting on the frontend but parse the actual integer in to the db.

Anyone have any ideas? There must be a way of doing this...

Hi Ben, would you be able to chat on Skype? Perhaps we can find a solution for this together.

I understand your issue now... The bad news is that I've no idea on how to make it work :( ...
Probably only with javascript.
I hope that someone else could give you a hand too :)

Hi,

I think you must use 2 system:
- Do all calculation in Hidden Equation question type.
- Show the result with 'text display' question tye (or put it in group description).

Example:
CALCUL1 : {sum(Q1,Q2,Q5)}
DISPLAY1 : {number_format(CALCUL1)}

Denis your post helped.

Now my next question, does the "number_format" function with EM allow to control decimal placement? It doesn't seem to, but I'm not a programmer and can't tell if it should or not.
