Since we're talking about integers, you can write 16*10**9 and the 
keyhole optimizer in recent versions of Python will do the maths for you 
at compile-time.

Or just write 16e9 and use a float.

By the way, I see at least one language (Frink) uses EE for exact 
integer exponents:

16e9 => float 16.0*1.0**9

16ee9 => int 16*10**9

Anyone think this is a good idea?
