Up and after ordering some things towards my wife's going into the country, to the office, where I spent the morning upon my measuring rules very pleasantly till noon, and then comes Creed and he and I talked about mathematiques, and he tells me of a way found out by Mr. Jonas Moore which he calls duodecimal arithmetique, which is properly applied to measuring, where all is ordered by inches, which are 12 in ❋ Samuel Pepys (1668)
Up and after ordering some things towards my wife's going into the country, to the office, where I spent the morning upon my measuring rules very pleasantly till noon, and then comes Creed and he and I talked about mathematiques, and he tells me of a way found out by Mr. Jonas Moore which he calls duodecimal arithmetique, which is properly applied to measuring, where all is ordered by inches, which are 12 in a foot, which I have a mind to learn. ❋ Samuel Pepys (1668)
It later changed its name to the Dozenal Society of America, since the word “duodecimal” was deemed to be overly reminiscent of the system they were aiming to replace. ❋ Alex Bellos (2010)
In arithmetic, and in other disciplines as well, truths remain the same even if notations are changed, and it does not matter whether a decimal or a duodecimal number system is used (Leibniz 1670, 128). ❋ Duncan, Stewart (2009)
Utopian of all things, a duodecimal system of counting. ❋ Herbert George (2006)
Our numbering system was a duodecimal one, and so it fit right in. ❋ Frankowski, Leo (2005)
Then came "the month of roses," as the Persians appropriately style that duodecimal portion of the year. ❋ Unknown (N/A)
Thus, 17 in the decimal scale would become 15 in the duodecimal; ❋ Levi Leonard Conant (N/A)
It is this element that has suggested the duodecimal base, to which some adhere so tenaciously, apparently because they have not ascertained the essential quality of a base. ❋ Various (N/A)
The development of astronomy implies considerable progress in mathematics; it is not surprising, therefore, that the Babylonians should have invented an extremely simple method of ciphering or have discovered the convenience of the duodecimal system. ❋ Various (N/A)
Thus, 7° 20 '10 "in circular measure, or 7' 20 "10 '' 'in duodecimal long measure. ❋ Alfred Rochefort Calhoun (N/A)
Two possible number systems that have, for purely theoretical reasons, attracted much attention, are the octonary and the duodecimal systems. ❋ Levi Leonard Conant (N/A)
Aside from our common decimal scale, there exist in the English language other methods of counting, some of them formal enough to be dignified by the term _system_ -- as the sexagesimal method of measuring time and angular magnitude; and the duodecimal system of reckoning, so extensively used in buying and selling. ❋ Levi Leonard Conant (N/A)
The duodecimal is not a natural scale in the same sense as are the quinary, the decimal, and the vigesimal; but it is a system which is called into being long after the complete development of one of the natural systems, solely because of the simple and familiar fractions into which its base is divided. ❋ Levi Leonard Conant (N/A)
From a commercial stand-point this advantage is very great; so great that many have seriously advocated the entire abolition of the decimal scale, and the substitution of the duodecimal in its stead. ❋ Levi Leonard Conant (N/A)
The armies were numbered by divisions of 8000; [373] and in countless other ways the vigesimal element of numbers entered into their lives, just as the decimal enters into ours; and it is to be supposed that they found it as useful and as convenient for all measuring purposes as we find our own system; as the tradesman of to-day finds the duodecimal system of commerce; or as the ❋ Levi Leonard Conant (N/A)
