New naming convention for large numbers

While maintaining the original system of the French mathematician Nicolas Chuquet (1484) for the names of large numbers, Jacques Pelletier promoted ''milliard'' for 10¹² which had been used earlier by Budaeus. In the late 17th century, ''milliard'' was subsequently reduced to 10⁹. This convention is used widely in long scale countries.
