Converting Binary Number to Decimal Number

How can we convert a binary number into a decimal number using a function in a programming language like Python?

Conversion from Binary to Decimal Number using Python

To convert a binary number into a decimal number, we can define a function in Python that performs the necessary mathematical operations. The function iterates through each digit of the binary number, multiplies it by 2 raised to the power of its position, and sums up the results to get the decimal equivalent. Let's break down the steps involved:

Define a Function:

1. Define a function named `BinaryToDecimal` that takes a binary number as input.

Validate Binary Input:

2. Check if the input consists only of '0' and '1' characters. If the input contains any other characters, display a warning message and return.

Initialize Variables:

3. Initialize a variable `decimal` to store the decimal equivalent and set it to 0.

4. Initialize a variable `power` to keep track of the position of the digit being processed and set it to 0.

Iterate Through Binary Number:

5. Iterate through each digit in the binary number from right to left.

6. For each digit, multiply it by 2 raised to the power of its position and add the result to the `decimal` variable.

7. Increment the `power` variable to move to the next position to the left.

Return Decimal Value:

8. Once all digits have been processed, return the final `decimal` value as the decimal equivalent of the binary number.

By following these steps, we can convert a binary number into its decimal form accurately and efficiently using a Python function.
