# How do you represent a positive number in two's complement?

**number**is commonly referred to as the sign-magnitude notation and if the sign bit is “0”, the

**number**is

**positive**. If the sign bit is “1”, then the

**number**is negative. When dealing with binary arithmetic operations, it is more convenient to use the

**complement**of the negative

**number**.

Furthermore, what is the 2's complement of a positive number?

The **two's complement of a positive number** is, when using this notation, a negative **number**. In order to flip the sign of a **number**, you always calculate the **two's complement** of that **number**: flip all bits, then add 1. Example: 3 in 8-bit signed binary notation is 00000011.

Beside above, what is the difference between the two's complement representation of a number and the two's complement of a number? The main **difference between** 1′ s **complement** and 2′ s **complement** is that 1′ s **complement** has **two** representations of 0 (zero) – 00000000, which is positive zero (+0) and 11111111, which is negative zero (-0); whereas **in** 2′ s **complement**, there is only one **representation** for zero – 00000000 (+0) because if we add 1 to

Simply so, how do you represent a number in two's complement?

**Two's complement** is the way every computer I know of chooses to **represent** integers. To get the **two's complement** negative notation of an integer, you write out the **number** in binary. You then invert the digits, and add one to the result.

What is the equivalent 2's complement representation?

Therefore, –15 in 16-bit decimal **representation** will be **represented** as 1000 0000 0000 1111. Now to find the **2's complement** of the 16-bit **representation** of above number first find the 1's **complement** and then add 1 to the result to obtain **2's complement**.
