Integer Type

Integer Type

Ruby's Integer type represents whole numbers of arbitrary size -- there's no fixed-width overflow like in many other languages, since Ruby automatically promotes to arbitrary precision as needed. Integer division truncates toward negative infinity. Every integer is an object, so you can call methods directly on a literal, like 5.times.

Note: Because integers are objects, you can call methods directly on a literal, like 3.even? or 5.times { ... }.

Example: Integer Type

x = 42
big = 123456789012345678901234567890

puts x.class
puts big
puts 7 / 2
puts 5.even?
