Public Instance Methods

byte()
Alias for: bytes
bytes() click to toggle source

Enables the use of byte calculations and declarations, like 45.bytes + 2.6.megabytes

# File lib/active_support/core_ext/numeric/bytes.rb, line 10
def bytes
  self
end
Also aliased as: byte
day()
Alias for: days
days() click to toggle source
# File lib/active_support/core_ext/numeric/time.rb, line 34
def days
  ActiveSupport::Duration.new(self * 24.hours, [[:days, self]])
end
Also aliased as: day
duplicable?() click to toggle source

Numbers are not duplicable:

3.duplicable? # => false
3.dup         # => TypeError: can't dup Fixnum
# File lib/active_support/core_ext/object/duplicable.rb, line 74
def duplicable?
  false
end
exabyte()
Alias for: exabytes
exabytes() click to toggle source
# File lib/active_support/core_ext/numeric/bytes.rb, line 40
def exabytes
  self * EXABYTE
end
Also aliased as: exabyte
fortnight()

fortnights() click to toggle source
# File lib/active_support/core_ext/numeric/time.rb, line 44
def fortnights
  ActiveSupport::Duration.new(self * 2.weeks, [[:days, self * 14]])
end
Also aliased as: fortnight
gigabyte()
Alias for: gigabytes
gigabytes() click to toggle source
# File lib/active_support/core_ext/numeric/bytes.rb, line 25
def gigabytes

html_safe?() click to toggle source
# File lib/active_support/core_ext/string/output_safety.rb, line 126
def html_safe?
  true
end
in_milliseconds() click to toggle source

Used with the standard time durations, like 1.hour.in_milliseconds – so we can feed them to JavaScript functions like getTime().

# File lib/active_support/core_ext/numeric/time.rb, line 51
def in_milliseconds
  self * 1000
end

second()
Alias for: seconds
seconds() 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.current.advance(months: 1)
1.month.from_now

# equivalent to Time.current.advance(years: 2)
2.years.from_now

# equivalent to Time.current.advance(months: 4, years: 5)
(4.months + 5.years).from_now
# File lib/active_support/core_ext/numeric/time.rb, line 19
def seconds
  ActiveSupport::Duration.new(self, [[:seconds, self]])
end
Also aliased as: second
