wait wait wait, a billion means two different things in Europe and America? I'm from Europe and I always used 1 billion to say 10^9. I hardly see how I would not have noticed figures being so different in say, news articles from America and Britain.
When I was growing up in Ireland, a billion was a million million in Britain and Ireland. Now, we have adopted the American thousand million. In Germany and Italy, a thousand million is a Milliard, and a billion is a trillion.
