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.
2. The act or art of reading numbers when
expressed by means of numerals. The term is almost exclusively
applied to the art of reading numbers written in the scale of tens,
by the Arabic method. Davies & Peck.
&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.
