Formats a number with grouped thousands using delimiter (e.g., 12,324). You can customize the format using optional delimiter and separator parameters.

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, ".")  # => 12.345.678

number_with_delimiter(98765432.98, " ", ",")
# => 98 765 432,98
