Thanks man, you're right:
The exact number is '609 012 571 758 190 248'.
609 012 571 758 190 thousand
609 012 571 758 million
609 012 571 billion
609 012 trillion (T)
I'm always confused when it comes to units in the English language. Here in Germany we have
Tausend = thousand
Million = million
Milliarde = billion
Billion = trillion
Trillion = quadrillion
So our 'Billion' is a trillion in English :) Maybe that's the reason why I came to the 'G'. I will change it to 'T' for the next version.
