Integer#<

self < other → true or false

Returns true if the value of self is less than that of other:

  1 < 0              # => false
  1 < 1              # => false
  1 < 2              # => true
  1 < 0.5            # => false
  1 < Rational(1, 2) # => false

Raises an exception if the comparison cannot be made.
