Subject: Math.log2 ?

Hello Group,

I wondered, why there is no log2 function in Math. I expected 
Math.log = log2 and
Math.ln = log_e.

And spend some time searching for the bug in my algorithm that used log2.

Now I use
module Math 
  def log2(n)
    Math.log(n) * 1.0 / Math.log(2)
  end
end

But this seems quite ugly to me. Is there a reason that log2 is missing,
or have I overlooked something.

Regards,

Brian
