How to find the truth value of the binary number of the complement, the process should be detailed f

That is, the minus sign, but the original code is waste, but it is also called the complement). , just replace the first digit with 1:

No matter how your teacher teaches you, ie.

You don't need this thing, then the "truth value" in your mouth is "-1".

So, if I have to say the original code, I can responsibly tell you that my method is absolutely correct, and the opposite).

Getting this number and converting it to decimal is 1.

Any computer complement as long as it is in the range, whether it is yes or negative (because although the positive number has not changed, it can be directly inverted and added to one, and the result is his opposite number, see here.)

This is the complement. It is also the source code.

It's also an anti-code. Positive complements.

Both the original code and the reverse code are the same.

If the complement is 1000

Then the reverse code is the complement code minus 1.

Then the original code is inverse code 1 becomes 0, and 0 becomes 1, that is.

The original code here has no symbol, so it is 32768

Add -, so the minimum value is.

How to find the truth value of the binary number of the complement code requires a detailed process.

Finding the truth from the complement is a very simple thing.

There is no need to ask for the "reverse code of the original code", nor do you need to think about "the symbol bit remains unchanged".

Either "minus one or negation" is not needed.

All you need to do is make a [number conversion].

The known eight-digit complement is

The first 1 represents both negative and 128 numbers.

The rest of the digits are all positive: 64 + 16 + 4 + 1 = 85.

The sum of you is the true value: 128 + 85 = 43.

If the complement is

The sum of you is the true value: 64 + 16 + 4 + 1 = +85.

11101110 binary conversion to decimal is to convert to decimal to 14*(16+1)=14*17=238, you can also convert 11101110 to hexadecimal ee, and then to decimal, e is 14 in decimal, so you get 14*16+14=238.

Finding the truth from the complement is a very simple thing.

You don't have to ask for the "reverse code of the original code", nor do you have to think about the "symbol bit unchanged".

Either "minus one or negation" is not needed.

You just do it[Digital system conversion], the result, will come outFinish.

The known eight-digit complement is

The 1 in the first position represents both a negative number and a 128.

The rest of the digits are all positive: 64 + 32 + 8 + 4 + 2 = 110.

The sum of you is the true value: 128 + 110 = 18.

If the complement is

The sum of you is the true value: 64 + 32 + 8 + 4 + 2 = 110.

13 128 is the decimal place.

It is necessary to follow the format of "fixed-point decimal" to find the original code, inverse code and complement code.

The binary of 13 128 is: 1101.

Let's assume that the code length is eight digits.

13 128 original code reverse code complement 0000 1101.

The original code for 13 128 is: 1000 1101.

The reverse code of 13 128 is: 1111 0010.

The complement of 13 128 is: 1111 0011.

According to the format requirements of "fixed point decimals", there is no need to mark the decimal point.

Its default position is after the sign bit.

Knowing the complement and finding the truth is very simple. You don't have to ask for the "reverse code of the original code", nor do you have to think about the "symbol bit unchanged".

"Take the reverse plus one.

or "minus one and take the negation, none of which are needed." You can directly carry out the [Socks Sakura Number System Conversion].

For example, if there is an eight-digit complement, yesThe first 1 represents both negative and 128 numbers.

The remainder of filial piety is positive: 16 + 8 + 4 + 2 = 30.

Find the sum, so the true value is: 98.

The other eight-digit complement isThe true value is: 16 + 8 + 4 + 2 = 30.

Simple or not? Unexpected or not unexpected?

Hello. The complementary code of a positive number is equal to the binary representation of the original number, that is, the original code.

The complement of the negative number is equal to the original code of its absolute value, and the value of the entire number of the orange backstool is added to 1.

Hope it helps.

Complement (two's complement)

1. In the computer system, the numerical values are always represented (stored) by the complement disadvantages.

The main reason is that with the use of complements, the symbol bits and other bits can be processed unified; At the same time, subtraction can also be handled by addition. In addition, two are used to make up.

When the numbers represented by the code are added, if the highest digit (sign bit) has a carry, the carry is discarded.

2. The conversion process between the complement code and the original code is almost the same.

Finding the complement of a given comic beat value is divided into the following two cases:

1) Positive complement: the same as the original code.

Example 1] The complement of +9 is 00001001.

2) the complement of negative numbers: the sign bit is 1, and the rest of the digits are the original code of the absolute value of the number by bit. Then add 1 to the whole number

52 Original code 10110100 ->> 11001011-" Complement 11001100

Summary. Find the binary number 1, the original, inverse and complement.

It's coming, don't worry.

Okay thank you. It's okay <>

Write out the binary truth of each complement of the row.

2.Use two's complement.

The following subtraction is calculated by addition (it is required to convert to binary ** first, and the calculation is calculated according to the subtraction method of binary 8-digit supplement letter code, and the results are discussed).

3.Use BCD code for decimal addition.

4.The known source code is called the complement.
