Converting a binary number into a decimal using a bitwise operator

In this recipe, you will learn how to convert a binary number into a decimal.

How to do it…

To convert a binary number into a decimal, perform the following steps:

1. Enter a binary number.
2. Apply a mod 10 (% 10) operator to the binary digits of the binary number to isolate the last bit of the binary number.
3. Left-shift the binary digit isolated in step 2 to multiply it by the power of 2. 
4. Add the product of the previous multiplication to the variable that will store the result, that is, the decimal number. Let's call the variable dec.
5. The last digit of the binary number is truncated.
6. Repeat step 2 to step 4 until...
