# Integer

### Public Instance Methods

month() click to toggle source
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. For example:

    # 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

While these methods provide precise calculation when used as in the examples above, care should be taken to note that this is not true if the result of `months’, `years’, etc is converted before use:

    # equivalent to 30.days.to_i.from_now
    1.month.to_i.from_now

    # equivalent to 365.25.days.to_f.from_now
    1.year.to_f.from_now

In such cases, Ruby’s core Date and Time should be used for precision date and time arithmetic

    # File lib/active_support/core_ext/integer/time.rb, line 30
    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

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 14
    def ordinalize
      ActiveSupport::Inflector.ordinalize(self)
    end

year() click to toggle source
Alias for: years
years() click to toggle source

    # File lib/active_support/core_ext/integer/time.rb, line 35
    def years
      ActiveSupport::Duration.new(self * 365.25.days, [[:years, self]])
    end

Also aliased as: year
