In today's world, computer plays a very significant role. It comes in different sizes, shapes and applications and had made our life simpler. The language used by the computers is in the form of binary numbers that is in 0 and 1 form .It is the lowest level that helps the machine to read. Computer usually works in binary but gives answer in decimals and that helps it to save the space. This is important as it simplifies the design of computer and related technologies. That's why it is considered as the perfect numbering system for computer. It is also considered easy and there is no comparison how much easier binary is than decimal. In this, we only need 2 digits, o and 1 while in decimal we need 10 digits that made the process much harder. It is a method of storing simple numbers such as 35 and 380 as pattern of 0's and 1's. Due to its digital nature, computers electronic can easily manipulate numbers stored in binary by treating as "on "and "off." Computers are having circuits that perform the arithmetical operations such as add, subtract, multiply, divide, and do many other things to numbers stored in binary.
The representation of numbers is essential for the digital logic design. In this chapter, positional number systems (decimal, binary, octal, hexadecimal), BCD and Gray codes are presented together with the rules for the conversion between numbers encoded in different bases and the representations of negative numbers. Then, the rules for the arithmetic operations and the circuits that execute them are presented. The addition of binary number is examined with particular attention, since it is the operation at the basis of all computational circuits. Alphanumeric codes and the concept of parity for error detection complete the chapter.

The Binary Number System Name • "binarius" (Latin) => two Characteristics • Two symbols • 0 1 • Positional • 1010 B ≠ 1100 B Most (digital) computers use the binary number system Terminology • Bit: a binary digit • Byte: (typically) 8 bits 6 Why?
Step 1: Divide the decimal number to be converted by the value of the new base. Step 2: Record the remainder from Step 1 as the rightmost digit (least significant digit) of the new base number. Step 3: Divide the quotient of the previous divide by the new base. Converting i.

If the base of a number system is larger than ten, the digits exceeding 9 are expressed using alphabet letters as a convention. For example, hexadecimal number system uses 1-9 and A-F; base-32 number system uses 1-9 and A-V. This example is shown in Table 1. One may then wonder how large-base number systems such as a base-64 are expressed.
8 Fynn and Emma Real Number System Real numbers can be represented on a number line (includes irrational and rational numbers.) Rational numbers can be written as a ratio/fraction. Irrational numbers cannot be expressed as a ratio/fraction because their decimal form does not end nor is it a repetitive pattern. Natural numbers are positive ...
Irrational Numbers (𝑄′) All numbers that cannot be written as where a and b are integers and 𝑏≠0. i.e. numbers that recur without a pattern Examples: 0,34791… -2,11816393… −6 317 And what about 0? , 0 is not an irrational number! Summary of the Number System

The Binary Number System The binary number system is also a positional numbering system. Instead of using ten digits, 0 - 9, the binary system uses only two digits, 0 and 1. Example of a binary number and the values of the positions: 1001 101 26 25 24 23 22 21 20. Converting from Binary to Decimal 101 26 25 24 23 22 21 20 20 1 21 = 2 25 = 32 22 ...
Example: 123410. Binary Number System • The binary number system is exactly like the decimal design except that the base is 2 instead of 10. • We have only two symbols or digits (0 and 1) that can be used in this number system Example: 10102. Octal Number System • In the octal number system the base is 8.
