Integer

month()

Alias for months

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

This method is also aliased as month

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

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"
