Add double dispatch to Integer. This class is the basis for the two concrete classes that hold whole numbers, Bignum and Fixnum. Public Class Methods In arithmetic, Euclidean division – or division with remainder – is the process of dividing one integer (the dividend) by another (the divisor), in a way that produces a quotient and a remainder smaller than the divisor. A fundamental property is that the quotient and the remainder exist and are unique, under some conditions. Because of this uniqueness, Euclidean division is often Ruby API is a Ruby on Rails app that makes browsing and searching Ruby's documentation easy and fast for users. 2.7 • 2.6 • 2.5 • master.

Fixnum is the class of all integers within a certain machine-dependent range that can be implemented more efficiently than Bignum can.

This enables multiple variables to be initialized with a single line of Ruby code. For example − a = 10 b = 20 c = 30 This may be more quickly declared using parallel assignment − a, b, c = 10, 20, 30 Parallel assignment is also useful for swapping the values held in two variables − a, b = b, c Ruby Bitwise Operators
