# class Integer

### Public Instance Methods

month()
Alias for: months
months() click to toggle source

Enables the use of time calculations and declarations, like `45.minutes + 2.hours + 4.years`.

These methods use Time#advance for precise date calculations when using `from_now`, `ago`, etc. as well as adding or subtracting their results from a Time object.

    # equivalent to Time.now.advance(months: 1)
    1.month.from_now

    # equivalent to Time.now.advance(years: 2)
    2.years.from_now

    # equivalent to Time.now.advance(months: 4, years: 5)
    (4.months + 5.years).from_now

    # File lib/active_support/core_ext/integer/time.rb, line 20
    def months
      ActiveSupport::Duration.new(self * 30.days, [[:months, self]])
    end

Also aliased as: month
multiple_of?(number) click to toggle source

Check whether the integer is evenly divisible by the argument.

    0.multiple_of?(0)  # => true
    6.multiple_of?(5)  # => false
    10.multiple_of?(2) # => true

    # File lib/active_support/core_ext/integer/multiple.rb, line 7
    def multiple_of?(number)
      number != 0 ? self % number == 0 : zero?
    end

ordinal() click to toggle source

Ordinal returns the suffix used to denote the position in an ordered sequence such as 1st, 2nd, 3rd, 4th.

    1.ordinal     # => "st"
    2.ordinal     # => "nd"
    1002.ordinal  # => "nd"
    1003.ordinal  # => "rd"
    -11.ordinal   # => "th"
    -1001.ordinal # => "st"

    # File lib/active_support/core_ext/integer/inflections.rb, line 26
    def ordinal
      ActiveSupport::Inflector.ordinal(self)
    end

ordinalize() click to toggle source

Ordinalize turns a number into an ordinal string used to denote the position in an ordered sequence such as 1st, 2nd, 3rd, 4th.

    1.ordinalize     # => "1st"
    2.ordinalize     # => "2nd"
    1002.ordinalize  # => "1002nd"
    1003.ordinalize  # => "1003rd"
    -11.ordinalize   # => "-11th"
    -1001.ordinalize # => "-1001st"

    # File lib/active_support/core_ext/integer/inflections.rb, line 13
    def ordinalize
      ActiveSupport::Inflector.ordinalize(self)
    end
