Re^5: extracting number from string

I you enclose bits of code in <c> and </c> tags the square brackets you typed will be preserved rather than being taken as some sort of link.

So, [\d.] denotes a character class consisting of digits and a full stop. Note that \d is in itself a character class which is the equivalent of [0-9]. Adding a comma is simplicity itself - [\d.,]. Have a look at perlretut and perlre for further information.

I hope this will be helpful.

Cheers,

Update: As AnomalousMonk points out, I totally forgot to explain the significance of the caret symbol at the start of a character class. Sorry!

And further, the regex metacharacter `^` at the beginning of a character set complements the characters specified in the set, so that `[^\d.,]` means "any character except a decimal digit, full-stop or comma".	[reply] [d/l] [select]
