Program Code – Understanding the Representation of Values in 2’s Complement Form

def to_bin(value, bits):
    '''
    Convert a decimal number to binary with 'bits' number of digits.
    Takes care of negative numbers by representing them in 2's complement.
    '''
    # 2's complement representation for negative numbers
    if value < 0:
        value = (1 << bits) + value
    # Binary formatting
    format_string = '{:0' + str(bits) + 'b}' 
    return format_string.format(value)

def from_bin(bin_str):
    '''
    Convert a binary number (as a string) to decimal.
    If the binary number is in 2's complement (for negative numbers), decipher accordingly.
    '''
    # If the first bit is 1, it's a negative number in 2's complement
    if bin_str[0] == '1':
        # Convert 2's complement to decimal
        return -1 * ((1 << len(bin_str)) - int(bin_str, 2))
    else:
        # It's a positive number, so convert directly
        return int(bin_str, 2)

# Example usage
if __name__ == '__main__':
    # Define the number of bits you want to use
    number_of_bits = 8

    # Positive number example
    pos_num = 27
    pos_bin = to_bin(pos_num, number_of_bits)
    print(pos_bin)

    # Negative number example
    neg_num = -27
    neg_bin = to_bin(neg_num, number_of_bits)
    print(neg_bin)

    # Convert back from binary to decimal
    print(from_bin(pos_bin))
    print(from_bin(neg_bin))

Code Output:

00011011    # Binary representation of positive 27
11100101    # 2's complement binary representation of negative -27
27          # Decimal conversion of 00011011
-27         # Decimal conversion of 11100101

Code Explanation:

Here’s the scoop folks, time for a scoop of brain freeze on twosie-complement flavah! Let’s crack the code. We got ourselves two slick functions: ‘to_bin’ and ‘from_bin’.

‘to_bin’ – Now that’s our little smarty-pants. It’ll juggle your decimal numbers and flip ‘em into binary. And no, it won’t leave the negative chums hangin’. It wraps ‘em up nice and cozy in 2’s complement wardrobe.

But how, you ask? Easy peasy. If your number’s throwing a fit and goes negative, ‘to_bin’ soothes it down with a ‘1 << bits’ lullaby plus the number itself – now that’s the trick for the 2’s complement serenade.

Now, don’t get started with tiny numbers, ’cause our ‘to_bin’ takes pride in precision. Tell it ‘how many bits’, and it’ll tailor your binary suit fit to a T. Oh, and that formatting string? That’s the sewing kit – crafts the binary with as many zeroes needed to fit the bill.

‘from_bin’ – The peacemaker. It’s gonna chill the bits down and turn that binary bouncer back to a decimal dude. But if it smells a ‘1’ upfront, it knows trouble’s cooking. It’s a sign of a 2’s complement with a mood swing.

So how does it calm the tantrum? By flipping the script: ‘1 << len(bin_str)’ for a full house, minus the binary boogie. The result? Sweet old decimal, back from its binary holiday.

And if that ‘1’ ain’t there? That means we’re just cool cats with a positive vibe. So ‘from_bin’ just cruises on with a straight decimal conversion. No 2’s complement hustle needed.

The finale? Python in action, with examples. Positive, negative, doesn’t matter – it reads ’em, flips ’em, and serves ’em back in wholesome decimal goodness. And it tells the world in console speak. Ain’t that a coder’s happy ending?

So there you have it – no more blues with twos, just a whole lot o’ binary fun. Don’t forget to thank your audience for tuning in – peace out and keep it bitwise, buddies! ✌👩‍💻
