#Numbers

Numbers take the form of Fixnum, Bignum (Class: Integer from Class: Numeric) or Float(Class: Numeric) there are others but they are part of the Standard Library, these are Complex, BigDecimal and Rational - these are not covered here. I can't be arsed. Sooo...

ruby-1.9.2-p0 > 5.class
 => Fixnum 
ruby-1.9.2-p0 > 5453897348957348957389457389457398.class
 => Bignum 
ruby-1.9.2-p0 > 5.0.class
 => Float

Variables

Local variables hold their value during a particular section of code. Local refers therefore to their 'scope' this can be seen through the value of the variable x below:

ruby-1.9.2-p0 > def support_united
ruby-1.9.2-p0 ?>  x = "I Support United"
ruby-1.9.2-p0 ?>  puts x
ruby-1.9.2-p0 ?>  end
ruby-1.9.2-p0 > def support_city
ruby-1.9.2-p0 ?>  x = "I Support City"

Self is not so much a concept as an object. The default object.

There is always only one self, but what that is may change. Like a narrator in a book with multiple first-person identities.

puts "top level"
puts "self is #{self}"

class C
 puts "Class Definition Block:"
