Re^2: Formating numbers with thousand separator - Solution for web-applications

[Zzenmonk]

Thx

This snippet is anyway only thought as a base. It needs to be customized for your requirements. I found this solution nice because it is short and easy to understand (and to debug!). Accordingly you can easily add features in JavaScript or PERL without ending up with a code monster. I use the same principle for example to format the IBAN account number (a financial standard to identify an account made of 12 to 34 alphanumeric characters) for display purposes.

As I searched the net I found a lot of solutions with regexp especially in the area of JavaScript. Things like /\B(?=(\d{3})+(?!\d))/'/g, if it may inspire you. I tried two or three of them and gave up because they did not work.

An expert in C would also tell you, there is a solution with the printf function family. Not being an expert, I could not find a format mask allowing for any number size (in fact it takes more time to read the man page than to write this).

Effectively this code is loosing the signs. It was designed to format amounts for a banking application. In this application the amounts are always positive. So I did not have the issue.
