[Maths Class Notes] on Decimal to Binary Pdf for Exam

It is important to convert a value from one number system to another number system. With this, we would be in a position to tell when the two different values will represent a similar amount. In the conversion of Decimal to Binary, we convert base 10 numbers to base 2 numbers using a simple procedure. For example, if the decimal number is (11)₁₀ then its equivalent binary number would be (1011)₂. In this article, we will discuss the conversion of Decimal to Binary Number Systems through Decimal to Binary number conversion examples.

Decimal to Binary Conversion Example

Here we will discuss the Decimal to Binary Conversion example:-

As we know, the Decimal Number System has base 10 and Binary Number System has base 2. While converting decimal numbers to binary numbers, the base of decimal numbers i.e. 10 will be changed into the base of the Conversion Binary Number System i.e. 2. All the decimal numbers retain their equivalent binary number. For example, if we want to convert (294)₁₀, then we will divide this number by 2. We will be left with some remainder and quotient value after dividing the given number by 2. The number will be divided by 2 till the quotient value reaches zero. As the quotient value reaches 2, place the remaining value in the series of Least Significant Bit (LSB) at the top and the Most Significant bit (MSB) at the bottom,

The binary numbers are most commonly used by computers for coding and programming purposes because the binary numbers system retains 2 digits 0 and 1 and computers only understand the language of the Binary Number System. (the )

 

Decimal to Binary Conversion Method

How to Convert a Decimal Number System to a Binary Number System?

To convert Decimal to Binary numbers, the following steps should be followed:-

Take any decimal number and divide it by “2″. After dividing, you will get some results along with the remainder.

If the decimal number chosen by you is even, then the result will be in a whole number and it will give the remainder 0.

If the decimal number chosen by you is odd, then the number will not be divided fully and you will get the remainder “1”.

Continue dividing the number till you get the quotient  0

Now place all the remainders in the series of Least Significant Bit (LSB) at the top and the Most Significant bit (MSB) at the bottom.

Based on the above steps, let us discuss the Decimal to Binary Conversion through example.

 

Let us Convert the Decimal Number 244 into a Binary Number.

Hence, 244₁₀ =11110100₂
