why the two's complement [010111.1100] is equal to 101000.0100?
all the steps are correct but when we add 1 to the first compliment the result is 101001.0011
example add the decimal number 45.23+2=47.23 but not 45.25.
The two's complement of a binary number is a way to represent negative numbers in binary form.
Step1:-
Start with the binary number you want to represent as a negative value that is : [010111.1100]
Step2:-
Invert (flip) all the bits, changing 0s to 1s and 1s to 0s. After inversion: [101000.0011]
Add 1 to the inverted number.
101000.0011 + 1 = 101000.0100
Which we can write as [101000.01]
