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
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.
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
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"
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"
