Jacques Pelletier du Mans (15171582) was a French mathematician. While maintaining the original system of Nicolas Chuquet, he proposed names for the intermediary numbers, at the time of the passage of the former grouping by six digits towards the modern grouping by three digits. (The hexadecimal numbers should be grouped by five digits. The modern internal 64 bits bus, that's 2 power 64 or F FFFFF FFFFF FFFFF units and the zero. Sixteen trillion hexadecimal units.) Thus he created, beside the Zillions already existing, the Zilliards. It's the use of nomination of the great numbers, having course in the world entireties, exempted the U.S.A., Brazil and Puerto Rico.

The system Chuquet-Pelletier remains incomparable and adapted for modern use.
