Jacques Pelletier du Mans

Jacques Pelletier du Mans (1517–1582) was a French mathematician. While maintaining the original system of Nicolas Chuquet, he proposed names for the intermediate numbers, when grouping by six digits moved towards the modern grouping by three digits. (The hexadecimal numbers should be grouped by five digits. The modern internal 64 bits bus can register 2⁶⁴ or F FFFFF FFFFF FFFFF units and the zero. Sixteen trillion hexadecimal units.) Thus he created, beside the Zillions already existing, the Zilliards. This convention is used throughout the world, except English-language countries, Brazil, Greece, Turkey, Russia and Puerto Rico.
