number_with_delimiter
number_with_delimiter(number, options = {})
public
Formats a number with grouped thousands using delimiter (e.g., 12,324). You can customize the format in the options hash.
Options
-
:locale - Sets the locale to be used for formatting (defaults to current locale).
-
:delimiter - Sets the thousands delimiter (defaults to “,”).
-
:separator - Sets the separator between the fractional and integer digits (defaults to “.”).
Examples
number_with_delimiter(12345678) # => 12,345,678 number_with_delimiter(12345678.05) # => 12,345,678.05 number_with_delimiter(12345678, :delimiter => ".") # => 12.345.678 number_with_delimiter(12345678, :separator => ",") # => 12,345,678 number_with_delimiter(12345678.05, :locale => :fr) # => 12 345 678,05 number_with_delimiter(98765432.98, :delimiter => " ", :separator => ",") # => 98 765 432,98
Alternative: use 1000.humanize
1.humanize == “1″ 1000000.humanize == “1.000.000″ 1000.12345.humanize == “1.000,12″

Deprecation warning for old-style options
You will get a warning if you don’t define your separators as a hash:
DEPRECATION WARNING: number_with_delimiter takes an option hash instead of separate delimiter and precision arguments
So while you can still use that style, it’s not without a scolding.
