I am just learning Ruby but it looks like the binary intersection of the
true bits. In shorter terms a binary "and" command.
3&6=2
in binary
011&110=010

3&7=3
in binary
011&111=011

7&21=5
in binary
00111&10101=00101

Hi Leo,

Thanks for your reply.

I am using Ruby 1.86 so http://www.ruby-doc.org/core/ will help me.

Methods that appear for instances of a particular class may be defined
in ancestors of that class (or included modules, either of the class
or its ancestors), rather than than in the class itself. In this case
__id__ and __send__ are Kernel methods (probably documented under
Object, rather than Kernel) and denominator is, I think, defined in
Numeric.

I spent more time to find the solution for all methods. So I created one
document which contains all the methods for that particular class.

Now it is available here

Fixnum:

String:
