Nu`mer*a"tion (?), n.
[L. numeratio a counting out: cf. F. numération.]
1. The act or art of numbering.
Numeration is but still
the adding of one unit more, and giving to the
whole a new
name or sign.
Locke.

&fist; For convenience in reading, numbers are usually separated by commas into periods of three figures each, as 1,155,465. 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.
