☞ For convenience in reading, numbers are usually separated by commas into periods of three figures each, as 1, 155, 465; in continental Europe, periods are used for a similar division. According to what is called the “English” system, the billion is a million of millions, a trillion a million of billions, and each higher denomination is a million times the one preceding. According to the system of the French and other Continental nations and also that of the United States, the billion is a thousand millions, and each higher denomination is a thousand times the preceding.
