Subject: Minor Change Proposal for Class 'Numeric'

Hi!

I didn't find there a discussion about this here, so first a description of this 
(very) minor change proposal.

I miss the "Sign function" in class "Numeric".

It can simply be added by something like...

class Numeric
   def sign
     self<0?-1:self>0?1:0
   end
end

...but it should be much faster if be defined in the original class.

This method will be used in several algorithms, so it should be available from 
my point of view.
