Instance Method Summary collapse

#months ⇒ Object
(also: #month)
Enables the use of time calculations and declarations, like 45.minutes + 2.hours + 4.years.

#multiple_of?(number) ⇒ Boolean
Check whether the integer is evenly divisible by the argument.

#ordinalize ⇒ Object
Ordinalize turns a number into an ordinal string used to denote the position in an ordered sequence such as 1st, 2nd, 3rd, 4th.
 #years ⇒ Object (also: #year)
Instance Method Details
#months ⇒ Object Also known as: month
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

#multiple_of?(number) ⇒ Boolean
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 ⇒ Object
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"
