Next, multiply this by 2, and add the next digit in your number (as you progress from left to right) to this product. To convert a binary integer to decimal, start by adding the left-most digit to 0. Let's look at two cases - converting binary integers to decimal, and then binary fractions to binary. So, 0.625 can be written as 0.101 in binary. Hence, just write these after the decimal point to get the binary notation. We see that the resulting integer parts of the product are 1, 0, 1. Multiply the fraction by 2 successively while noting the integer and fractional parts of the product. Now, write all the integer parts of the product in each step.įor example, let us convert the fraction 0.625 to binary. Keep multiplying each successive resulting fraction by 2 until you get a resulting fraction product of zero. Multiply the fraction by 2, while noting down the resulting integer and fraction parts of the product. To convert a fraction to binary, follow the opposite of the process described above. So, the decimal number 10 is represented as 1010 in binary. So, writing in reverse order, the number 15 in decimal is represented as 1111 in binary.įor an even integer, let's take the example of 10.
In this example, remainders are 1, 1, 1, 1. Next, write the all the remainders in reverse order. Divide the integer by 2 successively while noting the quotient and remainder. After this, just write all the remainders in reverse order to get the binary representation of the integer.įor example, let's convert the integer 15 to binary. Like this, keep dividing each successive quotient by 2 until you get a quotient of zero. Then, divide the quotient again by 2, and record the 3rd quotient and remainder. Divide the integer by 2, while noting the quotient and remainder. Let's look at two cases - converting decimal integers to binary, and then decimal fractions less than 1 to binary. Let's first take a look at the most common method used for conversion, and then delve deeper into the math behind the decimal-binary conversion. There are several methods and programs for converting decimal numbers to binary, and vice-versa.
