Numeration \Nu`mer*a"tion\, n. [L. numeratio a counting out: cf.
   F. num['e]ration.]
   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. 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.
