2.0 still create a column. And like Thomas: vote to "don't add it".

Thanks for your valuable feedback, Fred.

It's nice to hear that EM can handle that large amount of data and expressions and that the Excel import works so great.

I think there may be a bug in Expression Manager number_format. If you have an equation with result is a number greater than minus1000 or less than 1000, and try to number_format () it displays NAN. So any 1, 2, or 3-digit positive or negative and I get the NAN.

(I would report a bug but my account never works on the bugs site)

Funny I came across this php bug discussion about PHP number_format where Rasmus himself comments and gets in an argument with users
bugs.php.net/bug.php?id=50696

A very "interesting" discussion at the PHP bugtracker...

Fred, can you attach a sample survey? I'm not sure how this is implemented in detail at the EM but would like to test before submitting a ticket. Maybe the code is handled by PHP after being parsed by EM and thus the PHP bug causes the problem (just guessing))?!

It's not a number_format (not really).

number_format(10) return 10.

But if you do :
"some text"+number_format(10) : EM test if ("some text" AND number_format(10)) are string. And seems number_format(10) are not a string.

Think EM must do this:

10+10 = 20
"some text"+10 = "some text10".

And have a solution to do:
"10"+"10"="1010"

ACtually, EM test is strval(floatval("10"))=="10" and put is numeric if yes: think there are a conceptual bug here.

Thanks you guys!

A little bit off-topic, but I talked with Denis about creating a "format_money" function for EM. This would open up LimeSurvey to the wonderful world of finance. We need something that is like Excel currency masks and formatting.

Start with: -1234567.89
Turn it into: $(1,234,568) -- for example. there could be other

Currently you can write a function in EM to do this but there are a lot of steps. Especially when you can't count on number_format() even.

Also correction from earlier, it is not really a BUG in EM. Just a different expectation of how something will work.

Here is a pertinent quote from that PHP.net bug discussion:

Wow, a classic case of how not to treat unpaid volunteers who provide
critical pieces of your money-making infrastructure.

Think it's a bug or misfeature in EM.
