## Can a computer work with decimal number system?

unfortunately , computer cannot use decimal number system . instead it can use binary number system as it is using the lowest base number system used by us that is 2 .

## Why can’t computers use decimal numbers?

Because binary lends itself naturally to a ON-OFF system where ON means a current and OFF means no current. Using 10 different voltage levels would be very error prone. You could use binary numbers to represent decimal digits (this is called BCD).

Why is the decimal system important?

We use decimals every day while dealing with money, weight, length etc. Decimal numbers are used in situations where more precision is required than the whole numbers can provide. For example, when we calculate our weight on the weighing machine, we do not always find the weight equal to a whole number on the scale.

### What are disadvantages of using decimal number system?

Wasted storage and wasted time.

• A base 10 digit (0–9) requires 4 bits.
• A base 16 digit (0–9a-f) requires 4 bits.
• so 6 more values can be stored.
• Decimal arithmetic is rather slow… forced carries after 9 (binary 1001) is not efficient, and makes hardware more expensive.
• ### Why does computer use binary number system instead of decimal?

This two-state nature of the electronic components can be easily expresses with the help of binary numbers. The second reason is that computer circuits have to handle only two bits instead of 10 digits of the decimal system. This simplifies the design of the machine, reduces the cost and improves the reliability.

Why do computers use binary and not decimal?

Computers use binary – the digits 0 and 1 – to store data. The circuits in a computer’s processor are made up of billions of transistors . A transistor is a tiny switch that is activated by the electronic signals it receives. The digits 1 and 0 used in binary reflect the on and off states of a transistor.

#### What is decimal system in computer?

Decimal is a term that describes the base-10 number system, probably the most commonly used number system. The decimal number system consists of ten single- digit numbers: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. In computing, the binary , octal , or hexadecimal number system may be used instead of the decimal system.

#### What is the importance of number system in computer?

Encrypting important data, by converting figures into another number system to avoid hacking and misuse of data. It enables easy conversion of numbers for technical purposes. The entirety of computer architecture depends upon number systems (octal, hexadecimal).

What are the advantages of decimal system as compared to the other numerical systems which makes it the catalyst of the development of mathematics?

Here the binary positional system has been found to have great advantages over the decimal….The binary system.

decimal binary conversion
4 100 1 ( 22 ) + 0 ( 21 ) + 0 ( 20 )
5 101 1 ( 22 ) + 0 ( 21 ) + 1 ( 20 )
6 110 1 ( 22 ) + 1 ( 21 ) + 0 ( 20 )
7 111 1 ( 22 ) + 1 ( 21 ) + 1 ( 20 )

## Why binary numbers are important in computer system?

Binary numbers are important because using them instead of the decimal system simplifies the design of computers and related technologies. In every binary number, the first digit starting from the right side can equal 0 or 1. But if the second digit is 1, then it represents the number 2. If it is 0, then it is just 0.

## Why do computers work in binary and not say ternary?

In binary a unit (bit), can store 2 separate values. if you have ternary, then a unit can store 3 separate values.

What are the advantages of using binary number system?

The main advantage of using binary is that it is a base which is easily represented by electronic devices. The Binary Number System are also ease of use in coding, fewer computations and less computational errors.

### Why computer does not use decimal system to operate?

Well, I know, computer doesn’t use decimal (base 10) system to operate, it uses binary system, because there is a technical problem about transistors, and signals.

### Is it possible to design a computer that works with binary?

It is possible to design computers that work with numbers in decimal format, but many factors make binary easier to work with. Consider, for example, the process of adding two numbers. Doing this quickly requires identifying–as fast as possible–which digits will have carries out and which will have carries in.

Why do computers store numbers in human readable format?

Historically, it sometimes did make sense for computers to keep numbers stored in human-readable format. Many video games, for example, kept score using a sequence of decimal digits (which is why scores roll over at precise powers of ten, rather than at powers of two).

#### Why are digital computers so inefficiency?

Digital computers are, by comparison, trivial to program (hence, BASIC). Their inefficiency is irrelevant compared to their ease of use. However, this is because double-integration is a whomping difficult thing to do on paper, much less to describe such that a machine can process it.
