The Collaborative International Dictionary of English v.0.48:
Numeration \Nu`mer*a"tion\, n. [L. numeratio a counting out: cf.
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.
Note: 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.
[1913 Webster +PJC]
