2147483648 in binary is written as 10000000000000000000000000000000 because the binary system uses only two digits, 0 and 1, to represent numbers. This number system is used widely in computer systems. In this topic, we are going to learn about 2147483648 in the binary system.
The process of converting 2147483648 from decimal to binary involves dividing the number by 2. Here, it is getting divided by 2 because the binary number system uses only 2 digits (0 and 1). The quotient becomes the dividend in the next step, and the process continues until the quotient becomes 0.
This is a commonly used method to convert 2147483648 to binary. In the last step, the remainder is noted down from bottom to top, and that becomes the converted value. For example, the remainders noted down after dividing 2147483648 by 2 until getting 0 as the quotient is 10000000000000000000000000000000. Remember, the remainders here have been written upside down.
In the table shown below, the first column shows the binary digits (1 and 0) of 2147483648. The second column represents the place values of each digit, and the third column is the value calculation, where the binary digits are multiplied by their corresponding place values.
The results of the third column can be added to cross-check if 10000000000000000000000000000000 in binary is indeed 2147483648 in the decimal number system.
2147483648 can be converted easily from decimal to binary. The methods mentioned below will help us convert the number. Let’s see how it is done.
Expansion Method: Let us see the step-by-step process of converting 2147483648 using the expansion method.
Step 1 - Figure out the place values: In the binary system, each place value is a power of 2. Therefore, in the first step, we will ascertain the powers of 2. 20 = 1 21 = 2 22 = 4 ... 231 = 2147483648 Since 231 equals 2147483648, we stop at this power.
Step 2 - Identify the largest power of 2: In the previous step, we stopped at 231 because it equals 2147483648. This is the exact number we are converting, so write 1 in the 231 place. Since no subtraction is needed, all other places will be filled with 0s.
Step 3 - Identify the unused place values: Since we wrote 1 in the 231 place, we can just write 0s in all the remaining places, from 20 to 230. Now, by substituting the values, we get: 0 in the 20 place 0 in the 21 place ... 0 in the 230 place 1 in the 231 place
Step 4 - Write the values in reverse order: We now write the numbers upside down to represent 2147483648 in binary. Therefore, 10000000000000000000000000000000 is 2147483648 in binary.
Grouping Method: In this method, we divide the number 2147483648 by 2. Let us see the step-by-step conversion.
Step 1 - Divide the given number 2147483648 by 2. 2147483648 / 2 = 1073741824. Here, 1073741824 is the quotient and 0 is the remainder.
Step 2 - Continue dividing the quotient by 2 until the quotient becomes 0, noting down remainders at each step. This process will result in a series of 31 zeros followed by a 1 as the quotient becomes 0.
Step 3 - Write down the remainders from bottom to top. Therefore, 2147483648 (decimal) = 10000000000000000000000000000000 (binary).
There are certain rules to follow when converting any number to binary. Some of them are mentioned below:
This is one of the most commonly used rules to convert any number to binary. The place value method is the same as the expansion method, where we need to find the largest power of 2. Let’s see a brief step-by-step explanation to understand the first rule. Find the largest power of 2 less than or equal to 2147483648. Since the answer is 231, write 1 next to this power of 2. No subtraction is needed as 231 equals 2147483648. Write 0 next to the remaining powers (20 to 230). Final conversion will be 10000000000000000000000000000000.
The division by 2 method is the same as the grouping method. A brief step-by-step explanation is given below for better understanding. First, 2147483648 is divided by 2 to get 1073741824 as the quotient and 0 as the remainder. Continue dividing the quotient by 2 until the quotient becomes 0. Write the remainders upside down to get the binary equivalent of 2147483648, 10000000000000000000000000000000.
This rule also involves breaking the number into powers of 2. Identify the powers of 2 and write them down in decreasing order i.e., from 231 to 20. Find the largest power that fits into 2147483648. Allocate 1s and 0s to the suitable powers of 2. Combine the digits (0 and 1) to get the binary result.
The limitation of the binary system is that only 0s and 1s can be used to represent numbers. The system doesn’t use any other digits other than 0 and 1. This is a base 2 number system, where the binary places represent powers of 2. So, every digit is either a 0 or a 1. To convert 2147483648, we use 1 for 231 and 0s for all other powers.
