Integer

month()

months()

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

Also aliased as: month

  ActiveSupport::Duration.new(self * 30.days, [[:months, self]])
end

multiple_of?(number)

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

def multiple_of?(number)
  number != 0 ? self % number == 0 : zero?
end

ordinalize()

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"
