Formatted output for numbers with comma's?

[Wink Saville]

I was looking for a routine to convert a Number to a string with
comma's, is there a routine in the library for that?

It's not very hard to roll up a solution:

def commify( number )
number.to_s.reverse.gsub(/(\d\d\d)(?=\d)(?!\d*\.)/, '\1,').reverse
end

Hope that helps.

This would be a nice (ruby builtin) method


def commify( number, positions)
positions =3D 3 if positions =3D=3D nil
puts number.to_s.reverse.gsub(/(\d\d\d)(?=3D\d)(?!\d*\.)/, '\1,').rever=
se
^ not very sure how it would be done but something similar to
("\d"*positions)
end

puts commify(12345) # 12,345
puts commify(12345, 2) # 1,23,45

+1 vote as I've needed it quite a bit.

How would I/we go about getting something like this in stdlib?

have fun,
