Types of Number System

Number System is a method of representing Numbers on the
Number Line with the help of a set of Symbols and rules.
These symbols range from 0-9 and are termed as digits.
Number System is used to perform mathematical computations
ranging from great scientific calculations to calculations like
counting the number of Toys for a Kid or Number chocolates
remaining in the box. Number Systems comprise of multiple
types based on the base value for its digits.
Number System
Based on the base value and the number of allowed digits, number
systems are of many types. The four common types of Number
System are:
1.Decimal Number System
2.Binary Number System
3.Octal Number System
4.Hexadecimal Number System
Types of Number System
Number system 02
Number system with base value 10 is termed as Decimal
number system. It uses 10 digits i.e. 0-9 for the creation of
numbers. Here, each digit in the number is at a specific place
with place value a product of different powers of 10. Here,
the place value is termed from right to left as first place value
called units, second to the left as Tens, so on Hundreds,
Thousands, etc. Here, units has the place value as 100, tens
has the place value as 101, hundreds as 102, thousands as 103,
and so on.
Decimal Number System

• Number System with base value 2 is termed as Binary
number system. It uses 2 digits i.e. 0 and 1 for the creation
of numbers. The numbers formed using these two digits are
termed as Binary Numbers. Binary number system is very
useful in electronic devices and computer systems because
it can be easily performed using just two states ON and
OFF i.e. 0 and 1.
• Decimal Numbers 0-9 are represented in binary as: 0, 1, 10,
11, 100, 101, 110, 111, 1000, and 1001
Binary Number System
Number system 02
Octal Number System is one in which the base value is 8. It
uses 8 digits i.e. 0-7 for creation of Octal Numbers. Octal
Numbers can be converted to Decimal value by multiplying
each digit with the place value and then adding the result.
Here the place values are 80, 81, and 82. Octal Numbers are
useful for the representation of UTF8 Numbers.
Octal Number System
Number system 02
Number System with base value 16 is termed as
Hexadecimal Number System. It uses 16 digits for the
creation of its numbers. Digits from 0-9 are taken like the
digits in the decimal number system but the digits from 10-
15 are represented as A-F i.e. 10 is represented as A, 11 as
B, 12 as C, 13 as D, 14 as E, and 15 as F. Hexadecimal
Numbers are useful for handling memory address locations.
