Number formatting?

Robert Cowham

Any convenient ways (without rolling my own) of formatting numbers to
include thousands separators, e.g.

1199123 printed as "1,199,123"

This should be a FAQ. Does this group have a FAQ? :)

There are library modules that will do this for you, or you can
use the solution from the example in Friedl's book
_Mastering_Regular_Expressions_:

irb(main):001:0> 1199123.to_s.gsub(/(\d)(?=(\d\d\d)+(?!\d))/, '\1,')
=> "1,199,123"

Or any of several variants thereof.
