Understanding the Binary Number System

Before we dive into the conversion process, it’s crucial to have a basic understanding of the binary number system. In binary, each digit represents a power of 2, starting from the rightmost digit. For example, the binary number 1011 can be interpreted as (1 * 2^3) + (0 * 2^2) + (1 * 2^1) + (1 * 2^0).

Step-by-Step Detail of Binary to Decimal Converter

To convert a binary number to a decimal number, follow these steps:

  1. Start from the rightmost digit of the binary number.
  2. Assign the rightmost digit a value of 2^0, which is 1.
  3. Move to the next digit on the left and assign it a value of 2^1, which is 2.
  4. Continue this process, increasing the power of 2 by 1 for each subsequent digit.
  5. Multiply each digit by the corresponding power of 2.
  6. Sum up all the values obtained in the previous step to get the decimal equivalent.

Example of Binary to Decimal Converter

Let’s take the binary number 1101 as an example and convert it to decimal using the steps outlined above.

Starting from the rightmost digit: 1 * 2^0 = 1. b. Moving to the next digit: 0 * 2^1 = 0. c. Next digit: 1 * 2^2 = 4. d. Leftmost digit: 1 * 2^3 = 8. e. Summing up the values: 1 + 0 + 4 + 8 = 13.

Therefore, the binary number 1101 is equivalent to the decimal number 13.
