Nondecimal Positional Systems
M03_LONG0847_05_AIE_C03.qxd 9/17/07 10:38 AM Page 162 Not for Sale 162 CHAPTER 3 Numeration and Computation 3.2 Nondecimal Positional Systems In the preceding section, we discussed several numeration systems, including the decimal system in common use today. As already mentioned, the decimal system is a positional system based on 10. This is probably so because we have ten fingers and historically, as now, people often counted on their fingers. In the Did You Know box at the end of this section, we will give applications of positional systems that are based on whole numbers other than 10. One very useful application of bases other than ten is as a way to deepen our understanding of number systems, arithmetic in general, and our own decimal system. Although bases other than ten were in the K–5 curriculum in the past, they are not present currently. However, nondecimal positional systems are studied in the “math methods” course that is a part of an elementary education degree and may return to elementary school in the future. We will discuss addition and subtraction in base five in the next section and multiplication in base six in the following one. Base Five Notation For our purposes, perhaps the quickest route to understanding base five notation is to reconsider the abacus of Figure 3.1. This time, however, we allow only 5 beads to be moved forward on each wire. As before, we start with the wire to the students’ right (our left) and move 1 bead forward each time as we count 1, 2, 3, and so on. -
13054-Duodecimal.Pdf
Universal Multiple-Octet Coded Character Set International Organization for Standardization Organisation Internationale de Normalisation Международная организация по стандартизации Doc Type: Working Group Document Title: Proposal to encode Duodecimal Digit Forms in the UCS Author: Karl Pentzlin Status: Individual Contribution Action: For consideration by JTC1/SC2/WG2 and UTC Date: 2013-03-30 1. Introduction The duodecimal system (also called dozenal) is a positional numbering system using 12 as its base, similar to the well-known decimal (base 10) and hexadecimal (base 16) systems. Thus, it needs 12 digits, instead of ten digits like the decimal system. It is used by teachers to explain the decimal system by comparing it to an alternative, by hobbyists (see e.g. fig. 1), and by propagators who claim it being superior to the decimal system (mostly because thirds can be expressed by a finite number of digits in a "duodecimal point" presentation). • Besides mathematical and hobbyist publications, the duodecimal system has appeared as subject in the press (see e.g. [Bellos 2012] in the English newspaper "The Guardian" from 2012-12-12, where the lack of types to represent these digits correctly is explicitly stated). Such examples emphasize the need of the encoding of the digit forms proposed here. While it is common practice to represent the extra six digits needed for the hexadecimal system by the uppercase Latin capital letters A,B.C,D,E,F, there is no such established convention regarding the duodecimal system. Some proponents use the Latin letters T and E as the first letters of the English names of "ten" and "eleven" (which obviously is directly perceivable only for English speakers). -
Zero Displacement Ternary Number System: the Most Economical Way of Representing Numbers
Revista de Ciências da Computação, Volume III, Ano III, 2008, nº3 Zero Displacement Ternary Number System: the most economical way of representing numbers Fernando Guilherme Silvano Lobo Pimentel , Bank of Portugal, Email: [email protected] Abstract This paper concerns the efficiency of number systems. Following the identification of the most economical conventional integer number system, from a solid criteria, an improvement to such system’s representation economy is proposed which combines the representation efficiency of positional number systems without 0 with the possibility of representing the number 0. A modification to base 3 without 0 makes it possible to obtain a new number system which, according to the identified optimization criteria, becomes the most economic among all integer ones. Key Words: Positional Number Systems, Efficiency, Zero Resumo Este artigo aborda a questão da eficiência de sistemas de números. Partindo da identificação da mais económica base inteira de números de acordo com um critério preestabelecido, propõe-se um melhoramento à economia de representação nessa mesma base através da combinação da eficiência de representação de sistemas de números posicionais sem o zero com a possibilidade de representar o número zero. Uma modificação à base 3 sem zero permite a obtenção de um novo sistema de números que, de acordo com o critério de optimização identificado, é o sistema de representação mais económico entre os sistemas de números inteiros. Palavras-Chave: Sistemas de Números Posicionais, Eficiência, Zero 1 Introduction Counting systems are an indispensable tool in Computing Science. For reasons that are both technological and user friendliness, the performance of information processing depends heavily on the adopted numbering system. -

1 Issues with the Decimal Separator in Compound Creator (CC) We Have DWSIM 4.0 Installed in the Computer Classrooms, S
1 Issues with the decimal separator in Compound Creator (CC) We have DWSIM 4.0 installed in the computer classrooms, since we do the installation once in a semester (starting in February), so we haven’t updated the software in the classroom (though I have 4.3 in my desktop). With version 4.0, a team of students “created “ succinic acid with CC. They used the comma as decimal separator in Windows and in DWSIM, including CC. They used the experimental boiling point of succinic acid (they introduced 508,15 K, probably unnecessary decimal figures). However, when they added the database and created a stream of pure succinic acid, the model gave an error, failing to calculate the VLE in the stream (NRTL Nested Loops). When we edited de CC file, the boiling point in the General properties tab was shown as 5015: The comma had disappeared. And this seemed to be the source of the error. We fixed it by defining the dot as decimal separator in Windows and introducing 508.15 K in CC. Then it worked. I tried to reproduce the error some days later in DWSIM 4.3, but all worked perfectly: comma in Windows and comma in DWSIM including CC. Just an example of how the use of comma or dot can be a bit confusing for the user. Also, it seems that Compound Creator in DWSIM 4.3 allows to use the comma as decimal separator. I attach a PDF with the details of “everything apparently OK” with the comma in CC in 4.3. -

Decimal Sign in Sigmaplot
Decimal sign in SigmaPlot Data in the SigmaPlot worksheet can be text, numbers, or dates. Text is left-justified in the cell, numbers are right-justified. SigmaPlot works with decimal point or decimal comma, depending on the settings in Windows Control Panel > Regional and Language Options. Once a file has been imported, SigmaPlot “knows” the data format and displays it correctly. For importing however, the decimal sign format of the text file and of SigmaPlot must match. If they do not, there are two options: a) Set SigmaPlot to the settings which match those of the import file: close SigmaPlot, change the decimal settings in Windows, reopen SigmaPlot. b) Change the decimal sign in the text file to be imported. - You can do this in Notepad or any other editor (select all, replace). - Or you use one of the small utilities we have on our website (see below: 3. Utilities for decimal sign conversion). Background: SigmaPlot reads and applies the settings for decimal and list separators each time when it starts. There are two valid combinations: "point decimal" and "comma decimal". Either decimal separator = point list separator = comma or decimal separator = comma list separator = semicolon In Windows 2000, you find it under Control Panel > Regional Settings > Numbers. In Windows XP, you find it under Control Panel > Regional and Language Options > Regional Options > Customize > Numbers. In Windows 7, you find it under Control Panel > Region and Language > Formats > Additional settings > Numbers. This affects typing data into the worksheet, importing from text files, transforms language, and fit equation syntax. . -
Chapter 6 MISCELLANEOUS NUMBER BASES. the QUINARY
The Number Concept: Its Origin and Development By Levi Leonard Conant Ph. D. Chapter 6 MISCELLANEOUS NUMBER BASES. THE QUINARY SYSTEM. The origin of the quinary mode of counting has been discussed with some fulness in a preceding chapter, and upon that question but little more need be said. It is the first of the natural systems. When the savage has finished his count of the fingers of a single hand, he has reached this natural number base. At this point he ceases to use simple numbers, and begins the process of compounding. By some one of the numerous methods illustrated in earlier chapters, he passes from 5 to 10, using here the fingers of his second hand. He now has two fives; and, just as we say “twenty,” i.e. two tens, he says “two hands,” “the second hand finished,” “all the fingers,” “the fingers of both hands,” “all the fingers come to an end,” or, much more rarely, “one man.” That is, he is, in one of the many ways at his command, saying “two fives.” At 15 he has “three hands” or “one foot”; and at 20 he pauses with “four hands,” “hands and feet,” “both feet,” “all the fingers of hands and feet,” “hands and feet finished,” or, more probably, “one man.” All these modes of expression are strictly natural, and all have been found in the number scales which were, and in many cases still are, in daily use among the uncivilized races of mankind. In its structure the quinary is the simplest, the most primitive, of the natural systems. -

Results: i) The ratio of the circumference of a circle to its diameter is π . ii) The ratio of the width of a rectangular picture frame to its height is not necessarily equal to he golden ratio, though some artists and architects believe a frame made using the golden ratio makes the most pleasing and beautiful shape.iii) The ratio of two successive numbers of the Fibonacci sequence give an approximate value of the golden ratio,the bigger the pair of Fibonacci Numbers, the closer the approximation. Example1: The Golden Ratio = 1.61803398874989484820... = 1.618 correct to 3 decimal places. If x n are terms of the Fibonacci sequence, then what is the least value of n for which ( x n +1 / x n = 1.618 correct to 3 decimal places. Example2: A rectangle divided into a square and a smaller rectangle. If (x + y) /y = x / y ,find the value of golden ratio. Example3: The Golden Ratio = 1.61803398874989484820... = 1.6180 correct to 4 decimal places. If xn are terms of the Fibonacci sequence, then what is the least value of n for which (x n +1) / x n = 1.618 0 correct to 4 decimal places. Example4: Obtain golden ratio in a line segment. Proportion Proportion is an equation which defines that the two given ratios are equivalent to each other. -
The Counting System of the Incas in General, There Is a Lack of Material on the History of Numbers from the Pre-Columbian Americas
History of Numbers 1b. I can determine the number represented on an Inca counting board, and a quipu cord. The Counting System of the Incas In general, there is a lack of material on the history of numbers from the pre-Columbian Americas. Most of the information available concentrates on the eastern hemisphere, with Europe as the focus. Why? First, there has been a false assumption that indigenous peoples in the Americas lacked any specialized mathematics. Second, it seems at least some of their ancient mathematics has been intentionally kept secret. And Einally, when Europeans invaded and colonized the Americas, much of that evidence was most likely destroyed. In the 1960's, two researchers attempted to discover what mathematical knowledge was known by the Incas and how they used the Peruvian quipu, a counting system using cords and knots, in their mathematics. These researchers have come to certain beliefs about the quipu that are summarized below: Counting Boards It seems the Incas did not have a complicated system of computation. Whereas other peoples in the region, such as the Mayans, were doing computations related to their rituals and calendars, the Incas seem to have been more concerned with the task of record-keeping. To do this, they used what are called “quipu”(or khipu) to record quantities of items. However, they Eirst often needed to do computations whose results would be recorded on a quipu. To do these computations, they sometimes used a counting board or Yupana (from the Quechua word "yupay": count) made from a slab of wood or stone. -

Decimal Notation in the United States
Decimal Notation in the United States In the United States, we use the decimal or period (“.”) to represent the difference between whole numbers and partial numbers. We use the comma (“,”) to separate groups of three places on the whole numbers side. This might be different from the way you currently write numbers. For example, the number 1 million: Some non-U.S. Counties: 1.000.000,00 U.S.: 1,000,000.00 It is also very important to know the names for the digit places in decimal notation. Here are the names in English for the United States: Thousandths Trillions Hundred Billions Ten Billions Billions Hundred Millions Ten Millions Millions Hundred Thousands Ten Thousands Thousands Hundreds Tens Ones Tenths Hundredths Thousandths Ten Hundred Thousandths Millionths 1 , 2 3 4 , 5 6 7 , 8 9 0 , 1 2 3 . 4 5 6 7 8 9 Other than the “ones” place, the places to the right of the decimal are almost the same as the places to the left of the decimal, but with an additional “th” added at the end. How to Say Common Math Terms in U.S. English Numbers: Big Numbers: In the U.S. we separate big numbers into groups of three of the following types: Ones, Thousands, Millions, Billions, … For example: 1,234,567 has three groups Millions: 1 Thousands: 234 Ones: 567 We say each group as a separate number, followed by the group type. So, we would say: “One million, two hundred and thirty-four thousand, five hundred and sixty-seven” Decimals: When there is a decimal, we say it a few different ways: 0.4 can be expressed as “four tenths,” “zero point four,” or just
