What is a number system?
A number system is a method to represent (write) numbers. Every number system has a set of unique characters or literals. The count of these literals is called the radix or base of the number system. The four different number systems used in the context of computer are shown in Figure 2.2. These number systems are explained in subsequent sections.
What is the binary number system used for?
Operands used for calculations can be expressed in the binary number system. Other discrete elements including the decimal digits, are represented in binary codes. Data processing is carried out by means of binary logic elements using binary signals. Quantities are stored in binary storage elements.
What are the digits of the system?
These symbols are called the digits of the system. Any integer N is represented in the system by a sequence of base-b digits : N = a na n-1 ... a 1 a0 Then bkis the place value of a k , and N = a n × bn+ a n-1×b n-1+ ... + a 2× b 2+ a 1× b 1+ a 0× b 0 Number Systems Computer Basics 18 1.3 Decimal System
What are the digits of a positional number system?
Any positive integer b>1 can be chosen as the base for a positional number system similar to the decimal system (b=10) or the binary system (b=2). Such a system uses b symbols for the integers 0, 1, 2, 3, ..., b-1 These symbols are called the digits of the system.
