Advanced Ruby
These pages deal with some of the more advanced concepts of Ruby and are geared toward intermediate and advanced programmers. The covered concepts will build upon the more basic features of Ruby, a discussion of which can be found in Beginning Ruby.
Ruby's Bignum Library
Computers are quite good at math or, more precisely, at arithmetic. In fact, technically, that's all a computer can do. However, the numbers computers typically work with are quite limited. On a typical computer, an integer number is represented by a 32-bit binary number. A 32-bit integer can only represent the numbers from about negative 2 billion to positive 2 billion.

String Substitution in Ruby
Splitting a string is only one way to manipulate string data. You can also make substitutions to replace one part of a string with another string. For instance, in an example string "foo,bar,baz", replacing "foo" with "boo" in "foo,bar,baz" would yield "boo,bar,baz". You can do this and many more things using the sub and gsub method in the String class.
