In mathematics, binary and decimal numbers are the most commonly used number systems. Binary numbers have base 2. Binary numbers are generally used in computer applications, where binary numbers are represented by only two symbols or digits, i.e. 0 (zero) and 1 (one). The binary numbers here are expressed in the base-2 numeral system. For example, (120)_{2} is a binary number. Each digit in this system is said to be a bit.

In the **decimal number system**, the numbers are represented with base 10. The way of denoting the decimal numbers with base 10 is also termed as decimal notation. It is also called the base-10 number system, which consists of 10 digits, such as 0,1,2,3,4,5,6,7,8,9. This number system is widely used in computer applications. Each digit in the decimal system has a position, and every digit is ten times more significant than the previous digit.

However, it is possible to convert numbers from decimal to binary and binary to decimal. In this article, you will learn how to convert the decimal number 100 to a binary system.

## What is 100 in Binary?

The **binary equivalent of 100 is 1100100**. As we know, to convert any number from decimal system to binary, we have to divide the number by 2 and keep track of the remainder. To convert decimal to binary numbers, proceed with the steps given below:

- Divide the given decimal number by “2”, where it provides the result along with the remainder.
- If the given decimal number is even, then the result will be a whole number, and it provides the remainder with “0.”
- If the given decimal number is odd, then the result is not appropriately divided, and it provides the remainder with “1”.
- By placing all the remainders in order in such a way, the Least Significant Bit (LSB) at the top and Most Significant Bit (MSB) at the bottom, the required binary number will be obtained.

The below figure shows the conversion of the number 100 to binary number.

### 100 in Binary to Decimal

We have converted the decimal number 100 into binary. In this section, you can learn how to convert binary to decimal, i.e. (1100100)_{2} to decimal. For this, we can use the formula given below:

Where,

N is decimal equivalent,

b is the digit,

q is the base value that starts from the most significant digit order q^{n} to least significant order q^{-1}, q-2, …..

In other words, we need to multiply each digit of the binary number by the corresponding power of 2 and then sum up to get the required decimal value.

(1100100)_{2} = 1 x 2^{6} + 1 x 2^{5} + 0 x 2^{4} + 0 x 2^{3} + 1 x 2^{2} + 0 x 2^{1} + 0 x 2^{0}

= 64 + 32 + 0 + 0 + 4 + 0 + 0

= 100

Therefore, (1100100)_{2} = (100)_{10}
