Computer Methods in Chemical Engineering
Table of Contents
Computer uses the binary system. Any physical system that can exist in two distinct states (e.g., 0-1, on-off, hi-lo, yes-no, up-down, north-south, etc.) has the potential of being used to represent numbers or characters. A binary digit is called a bit . There are two possible states in a bit, usually expressed as and 1. A series of eight bits strung together makes a byte , much as 12 makes a dozen. With 8 bits, or 8 binary digits, there exist 2^ =256 possible combinations. The following table shows some of these combinations. (The number enclosed in parentheses represents the decimal equivalent.)
=1024 is commonly referred to as a "K". It is approximately equal to one thousand. Thus, 1 Kbyte is 1024 bytes. Likewise, 1024K is referred to as a "Meg". It is approximately equal to a million. 1 Mega byte is 1024*1024=1,048,576 bytes. If you remember that 1 byte equals one alphabetical letter, you can develop a good feel for size.
Number System
You may regard each digit as a box that can hold a number. In the binary system, there can be only two choices for this number either a "0" or a "1". In the octal system, there can be eight possibilities:

Positional number systems
Our decimal number system is known as a positional number system, because the value of the number depends on the position of the digits. For example, the number has a very different value than the number , although the same digits are used in both numbers. (Although we are accustomed to our decimal number system, which is positional, other ancient number systems, such as the Egyptian number system were not positional, but rather used many additional symbols to represent larger values.) In a positional number system, the value of each digit is determined by which place it appears in the full number. The lowest place value is the rightmost position, and each successive position to the left has a higher place value. In our decimal number system, the rightmost position represents the "ones" column, the next position represents the "tens" column, the next position represents "hundreds", etc. Therefore, the number represents hundred and tens and ones, whereas the number

The Babylonian civilisation in Mesopotamia replaced the Sumerian civilisation and the Akkadian civilisation. We give a little historical background to these events in our article Babylonian mathematics . Certainly in terms of their number system the Babylonians inherited ideas from the Sumerians and from the Akkadians. From the number systems of these earlier peoples came the base of 60, that is the sexagesimal system. Yet neither the Sumerian nor the Akkadian system was a positional system and this advance by the Babylonians was undoubtedly their greatest achievement in terms of developing the number system. Some would argue that it was their biggest achievement in mathematics. Often when told that the Babylonian number system was base 60 people's first reaction is: what a lot of special number symbols they must have had to learn. Now of course this comment is based on knowledge of our own decimal system which is a positional system with nine special symbols and a zero symbol to denote an empty place. However, rather than have to learn 10 symbols as we do to use our decimal numbers, the Babylonians only had to learn two symbols to produce their base 60 positional system. Now although the Babylonian system was a positional base 60 system, it had some vestiges of a base 10 system within it. This is because the 59 numbers, which go into one of the places of the system, were built from a 'unit' symbol and a 'ten' symbol.

The Real Number System
The real number system evolved over time by expanding the notion of what we mean by the word “number.” At first, “number” meant something you could count, like how many sheep a farmer owns. These are called the natural numbers , or sometimes the counting numbers
Natural Numbers
or “Counting Numbers”
  • The use of three dots at the end of the list is a common mathematical notation to indicate that the list keeps going forever.
At some point, the idea of “zero” came to be considered as a number. If the farmer does not have any sheep, then the number of sheep that the farmer owns is zero. We call the set of natural numbers plus the number zero the whole numbers
Whole Numbers
Natural Numbers together with “zero”
About the Number Zero
What is zero? Is it a number? How can the number of nothing be a number? Is zero nothing, or is it something? Well, before this starts to sound like a Zen koan, let’s look at how we use the numeral “0.” Arab and Indian scholars were the first to use zero to develop the place-value number system that we use today. When we write a number, we use only the ten numerals 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. These numerals can stand for ones, tens, hundreds, or whatever depending on their position in the number. In order for this to work, we have to have a way to mark an empty place in a number, or the place values won’t come out right. This is what the numeral “0” does. Think of it as an empty container, signifying that that place is empty. For example, the number 302 has 3 hundreds, no tens, and 2 ones.

Binary Number System
The Binary Number Base Systems
Most modern computer systems (including the IBM PC) operate using binary logic. The computer represents values using two voltage levels (usually 0V for logic and either +3.3 V or +5V for logic 1). With two levels we can represent exactly two different values. These could be any two different values, but by convention we use the values zero and one. These two values, coincidentally, correspond to the two digits used by the binary number system. Since there is a correspondence between the logic levels used by the computer and the two digits used in the binary numbering system, it should come as no surprise that computers employ the binary system. The binary number system works like the decimal number system except the Binary Number System:
uses base 2 includes only the digits and 1 (any other digit would make the number an invalid binary number)
The weighted values for each position is determined as follows: In the United States among other countries, every three decimal digits is separated with a comma to make larger numbers easier to read. For example, 123,456,789 is much easier to read and comprehend than 123456789. We will adopt a similar convention for binary numbers. To make binary numbers more readable, we will add a space every four digits starting from the least significant digit on the left of the decimal point. For example, the binary value 1010111110110010 will be written 1010 1111 1011 0010.

The Hexadecimal Number Base System
A big problem with the binary system is verbosity. To represent the value 202 requires eight binary digits. The decimal version requires only three decimal digits and, thus, represents numbers much more compactly than does the binary numbering system. This fact was not lost on the engineers who designed binary computer systems. When dealing with large values, binary numbers quickly become too unwieldy. The hexadecimal (base 16) numbering system solves these problems. Hexadecimal numbers offer the two features:
  • hex numbers are very compact it is easy to convert from hex to binary and binary to hex.
Since we'll often need to enter hexadecimal numbers into the computer system, we'll need a different mechanism for representing hexadecimal numbers since you cannot enter a subscript to denote the radix of the associated value. The Hexadecimal system is based on the binary system using a Nibble or 4-bit boundary. In Assembly Language programming, most assemblers require the first digit of a hexadecimal number to be 0, and we place an H at the end of the number to denote the number base. The Hexadecimal Number System:
uses base 16 includes only the digits through 9 and the letters A, B, C, D, E, and F

The Egyptian Number System For most people maths is numbers is arithmetic. So where better place to start than with the Ancient Egyptian numbers themselves. Their number system was decimal in nature but did not make use of place value. As a result of this, they didn't have a symbol for zero. These are the hieroglyphs: I always think the number for a million looks as though the person is holding out his arms in amazement at how unbelievably big it is! So the number 1,342 would look like this: Notice how they stack the hieroglyphs rather than writing them in one straight line. Now try one yourself.......
How would an Ancient Egyptian write the number 2,563? Click here to find out the answer Fractions Now you've got the idea of whole numbers let's look at fractions. The Ancient Egyptians used unit fractions e.g. e.g 1/4, 1/7, 1/15. Unit fractions are those fractions which have the number 1 as nominator (the number on the top). Their usual way of writing fractions was to use the word r, meaning part, with the denominator written below and, if need be, beside it as well e.g. ="part 12" which is equivalent to our twelfth or 1/12.

CBE number system
Though scientific publications document sources in similar ways, the details of presenting source information vary from journal to journal. Often publications provide prospective authors with style sheets that outline formats for presenting sources. Before submitting an article to a scientific publication, you should request its style sheet. If one is not available, examine a copy of the publication to see how sources are listed. When writing for a science course, check with your instructor about which format to use.
Biologists, zoologists, earth scientists, geneticists, and other scientists may use an author-date system of documentation (one type of author-date system is shown in the APA documentation section of this booklet). Or they may use a number system in which each source is given a number in the text. Following the text, full publication information for each numbered source is provided in a list of references. Entries in this list are given in the order in which they are mentioned in the paper.
One type of number system is outlined in Scientific Style and Format , published by the Council of Biology Editors (6th ed., 1994). In the paper, the source is referenced by a superscript number:

What is it?
The Interim NHS Number System (INNS) is intended for use in Trusts that will not be using any of the maternity systems from the suppliers listed on the Suppliers Page , along with sites that still generate birth notifications manually. INNS has been developed by our partners Syntegra and will continue to be issued free of charge to all requesting sites. It provides facilities that will connect you directly to the Central Issue System and will enable you to:
  • Create an electronic Birth Notification Obtain an NHS number Print labels and standard reports Extract information for local analysis Maintain an audit of transactions
As existing manual sites will be using INNS, we have ensured that ease of use was a design priority.
Trusts are expected to provide the hardware to run INNS. Details of the minimum specification for hardware have been published. The project team are maintaining contact with all sites that have expressed an interest in INNS.

Number 26 September Equinox 1997 NUMBER SYSTEMS AND CALENDARS OF THE BERBER POPULATIONS OF GRAND CANARY AND TENERIFE
by Jose Barrios Garca In the 14-15th centuries Grand Canary and Tenerife were inhabited by Berber populations, called Canarians and Guanches. They presumably came from the nearby continent on different occasions between the first millennium BC and the first millennium AD. These populations remained relatively isolated until the European rediscovery of the Islands in late 13th century. At this time the population of each Island was about 40-60,000 inhabitants, sustaining a developed agricultural (barley, wheat) and stock raising (goats, sheep, pigs) economy. Written sources from c. 1300 AD on certify the arithmetical and calendrical activities of these groups. On this basis, I started the research on the mathematical and astronomical practices of these people that crystallized into my doctoral dissertation (editors note: congratulations to Jose for his recent defense of thesis at the University of La Laguna, Tenerife). For each Island the study considered: 1) the economical, social, political and religious organization of the Island 2) the written and archaeological evidence regarding numerical and calendrical activities 3) the economic and cultural context of the number systems and the calendars.
