An Integer object represents an integer value.

You can create an Integer object explicitly with:

• An integer literal.

You can convert certain objects to Integers with:

• Method Integer.

An attempt to add a singleton method to an instance of this class causes an exception to be raised.

What’s Here

First, what’s elsewhere. Class Integer:

• Inherits from class Numeric.

Here, class Integer provides methods for:

• Querying

• Comparing

• Converting

• Other

Querying

• allbits?: Returns whether all bits in self are set.

• anybits?: Returns whether any bits in self are set.

• nobits?: Returns whether no bits in self are set.

Comparing

• <: Returns whether self is less than the given value.

• <=: Returns whether self is less than or equal to the given value.

• <=>: Returns a number indicating whether self is less than, equal to, or greater than the given value.

• == (aliased as ===): Returns whether self is equal to the given

  value.

• >: Returns whether self is greater than the given value.

• >=: Returns whether self is greater than or equal to the given value.

Converting

• ::sqrt: Returns the integer square root of the given value.

• ::try_convert: Returns the given value converted to an Integer.

• % (aliased as modulo): Returns self modulo the given value.

• &: Returns the bitwise AND of self and the given value.

• *: Returns the product of self and the given value.

• **: Returns the value of self raised to the power of the given value.

• +: Returns the sum of self and the given value.

• -: Returns the difference of self and the given value.

• /: Returns the quotient of self and the given value.

• <<: Returns the value of self after a leftward bit-shift.

• >>: Returns the value of self after a rightward bit-shift.

• []: Returns a slice of bits from self.

• ^: Returns the bitwise EXCLUSIVE OR of self and the given value.

• ceil: Returns the smallest number greater than or equal to self.

• chr: Returns a 1-character string containing the character represented by the value of self.

• digits: Returns an array of integers representing the base-radix digits of self.

• div: Returns the integer result of dividing self by the given value.

• divmod: Returns a 2-element array containing the quotient and remainder results of dividing self by the given value.

• fdiv: Returns the Float result of dividing self by the given value.

• floor: Returns the greatest number smaller than or equal to self.

• pow: Returns the modular exponentiation of self.

• pred: Returns the integer predecessor of self.

• remainder: Returns the remainder after dividing self by the given value.

• round: Returns self rounded to the nearest value with the given precision.

• succ (aliased as next): Returns the integer successor of self.

• to_f: Returns self converted to a Float.

• to_s (aliased as inspect): Returns a string containing the place-value representation of self in the given radix.

• truncate: Returns self truncated to the given precision.

• |: Returns the bitwise OR of self and the given value.

Other

• downto: Calls the given block with each integer value from self down to the given value.

• times: Calls the given block self times with each integer in (0..self-1).

• upto: Calls the given block with each integer value from self up to the given value.

Raised when an invalid operation is attempted on a Fiber, in particular when attempting to call/resume a dead fiber, attempting to yield from the root fiber, or calling a fiber across threads.

fiber = Fiber.new{}
fiber.resume #=> nil
fiber.resume #=> FiberError: dead fiber called

Raised when a given numerical value is out of range.

[1, 2, 3].drop(1 << 100)

raises the exception:

RangeError: bignum too big to convert into `long'

Raised when a file required (a Ruby script, extension library, …) fails to load.

require 'this/file/does/not/exist'

raises the exception:

LoadError: no such file to load -- this/file/does/not/exist

EncodingError is the base class for encoding errors.

TCPServer represents a TCP/IP server socket.

A simple TCP server may look like:

require 'socket'

server = TCPServer.new 2000 # Server bind to port 2000
loop do
  client = server.accept    # Wait for a client to connect
  client.puts "Hello !"
  client.puts "Time is #{Time.now}"
  client.close
end

A more usable server (serving multiple clients):

require 'socket'

server = TCPServer.new 2000
loop do
  Thread.start(server.accept) do |client|
    client.puts "Hello !"
    client.puts "Time is #{Time.now}"
    client.close
  end
end
