Signed binary one's complement number 0000 0000 0000 0000 converted to decimal system (base ten) signed integer

How to convert a signed binary one's complement: 0000 0000 0000 0000_{(2)} to an integer in decimal system (in base 10)

1. Is this a positive or a negative number?

In a signed binary one's complement, first bit (the leftmost) indicates the sign, 1 = negative, 0 = positive.

0000 0000 0000 0000 is the binary representation of a positive integer, on 16 bits (2 Bytes).

2. Get the binary representation of the positive (unsigned) number:

* Run this step only if the number is negative *

Flip all the bits in the signed binary one's complement representation (reverse the digits) - replace the bits set on 1 with 0s and the bits on 0 with 1s:

* Not the case *

3. Map the unsigned binary number's digits versus the corresponding powers of 2 that their place value represent:

4. Multiply each bit by its corresponding power of 2 and add all the terms up:

5. If needed, adjust the sign of the integer number by the first digit (leftmost) of the signed binary:

0000 0000 0000 0000_{(2)} = 0_{(10)}

Conclusion:

Number 0000 0000 0000 0000_{(2)} converted from signed binary one's complement representation to an integer in decimal system (in base 10):

0000 0000 0000 0000_{(2)} = 0_{(10)}

Spaces used to group numbers digits: for binary, by 4.

Convert signed binary one's complement numbers to decimal system (base ten) integers

Entered binary number length must be: 2, 4, 8, 16, 32, or 64 - otherwise extra bits on 0 will be added in front (to the left).

How to convert a signed binary number in one's complement representation to an integer in base ten:

1) In a signed binary one's complement, first bit (leftmost) indicates the sign, 1 = negative, 0 = positive.

2) Construct the unsigned binary number: flip all the bits in the signed binary one's complement representation (reversing the digits) - replace the bits set on 1 with 0s and the bits on 0 with 1s.

3) Multiply each bit of the binary number by its corresponding power of 2 that its place value represents.

4) Add all the terms up to get the positive integer number in base ten.

5) Adjust the sign of the integer number by the first bit of the initial binary number.

How to convert signed binary numbers in one's complement representation from binary system to decimal

To understand how to convert a signed binary number in one's complement representation from binary system to decimal (base ten), the easiest way is to do it through an example - convert binary, 1001 1101, to base ten:

In a signed binary one's complement, first bit (leftmost) indicates the sign, 1 = negative, 0 = positive. The first bit is 1, so our number is negative.

Get the binary representation of the positive number, flip all the bits in the signed binary one's complement representation (reversing the digits) - replace the bits set on 1 with 0s and the bits on 0 with 1s: !(1001 1101) = 0110 0010

Write bellow the positive binary number representation in base two, and above each bit that makes up the binary number write the corresponding power of 2 (numeral base) that its place value represents, starting with zero, from the right of the number (rightmost bit), walking to the left of the number by increasing each corresonding power of 2 by exactly one unit:
