number_with_delimiter(number, *args) public

Formats a number with grouped thousands using delimiter (e.g., 12,324). You can customize the format in the options hash.

Options

:delimiter - Sets the thousands delimiter (defaults to ",").
:separator - Sets the separator between the units (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(98765432.98, :delimiter => " ", :separator => ",")
 # => 98 765 432,98

You can still use number_with_delimiter with the old API that accepts the delimiter as its optional second and the separator as its optional third parameter:

 number_with_delimiter(12345678, " ")                     # => 12 345.678
 number_with_delimiter(12345678.05, ".", ",")             # => 12.345.678,05

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.
