adding comma's... formatting numbers

powerhouse has asked for the wisdom of the Perl Monks concerning the following question:

I've searched and searched, but don't know what to search for. can you please tell me what to search for, to format a number, say, 1000000 to add the comma's where they should be to look right, such as 1,000,000?

I've done super search, I've searched for tons of keywords, but cannot find anything that show's me how to format, even a phone number, or anything that is remotely close.

I would deeply appreciate any pointers into the right direction

thx,
Richard

....I've searched for tons of keywords.... But did you search CPAN? Searching for format number brings up the lovely Number::Format, which does exactly what you want (look at THOUSANDS_SEP). davis It's not easy to juggle a pregnant wife and a troubled child, but somehow I managed to fit in eight hours of TV a day.

The common term is "commify". There's quite a bit of code floating around, as it's a less trivial problem than would appear to be at first. There's even a couple of snippets in perlfaq5: How can I output my numbers with commas added?.	[reply]

The following code will comma-fy floating numbers, like 10000.00 into 10,000.00. Which I think would be more useful to you than one that formats just integers. `{ local $_ = $amount; /\./ ? s/(?<=\d)(?=(\d{3})+(?:\.))/,/g : s/(?<=\d)(?=(\d{3})+(?!\d))/,/g; $amount = $_; }` [download]	[reply] [d/l]

I've done super search, I've searched for tons of keywords, but cannot find anything that show's me how to format, even a phone number, or anything that is remotely close. And the answer was there on your own box all the time. It's in the perlfaq, and a simple `perldoc -q commas` would have revealed it. Abigail	[reply]
