Format phone number in Rails

Recently, I have needed to take a number string and format it to a phone number. This was a PITA in PHP, fortunately, Rails includes some methods that will make the formatting of phone numbers much easier.

# number_to_phone(number, options = {})
# Formats a number into a US phone number (e.g., (555) 123-9876).
# You can customize the format in the options hash.
#
# Options
#
# :area_code - Adds parentheses around the area code.
# :delimiter - Specifies the delimiter to use (defaults to "-").
# :extension - Specifies an extension to add to the end of the generated number.
# :country_code - Sets the country code for the phone number.

# returns => 123-555-1234
number_to_phone(1235551234)

# returns => (123) 555-1234
number_to_phone(1235551234, :area_code => true)

# returns => 123 555 1234
number_to_phone(1235551234, :delimiter => " ")

# returns => (123) 555-1234 x 555
number_to_phone(1235551234, :area_code => true, :extension => 555)

# returns => +1-123-555-1234
number_to_phone(1235551234, :country_code => 1)    

# returns => +1.123.555.1234 x 1343
number_to_phone(1235551234, :country_code => 1, :extension => 1343, :delimiter => ".")

Rails number to percentage helper

In the next few days I’m going to quickly touch on a few of Rail’s number helper methods. Lately I’ve been doing a lot of mathematical calculations that require percentages, the number_to_percentage method is quite handy.

# number_to_percentage(number, options = {})
#  Formats a number as a percentage string (e.g., 65%). You can customize the format in the options hash.
# Options
#  :codecision - Sets the level of codecision (defaults to 3).
#  :separator - Sets the separator between the units (defaults to ".").
# Examples

# returns 100.000%
number_to_percentage(100)                        

# returns 100%
number_to_percentage(100, :codecision => 0)        

# returns 302.24399%
number_to_percentage(302.24398923423, :codecision => 5)
