What binary numbers have you come across?

The binary of 12 is 1100 and the ternary is 110; The binary of 13 is 1101 and the ternary is 111; The binary of 14 is 1110 and the ternary is 112. This group is funny, the first two are the same (11), and the second is just two or three (00 01 10vs0 1 2).

Which, it seems that I haven't really met it. There's a Nimes game though, which requires binary to win.

Binary, every two into one, the data is only represented by 0 and 1, so the numbers you see are 0 and 1, and the others are gone.

Binary is actually the same as the daily decimal system, in which the decimal system is every 10 into one place, and the binary system is every 2 into one place. In binary, there are only two digits per bit, 0 and 1, and 3 is 00000011.

Binary is a system of numbers that is widely used in computing technology. Binary digits are numbers represented by two numbers, 0 and 1. Its base is 2, the carry rule is "every two into one", and the borrowing rule is "borrow one as two".

Binary is to be carried when it is equal to 2, for example:

That is, every two into one.

Binary is an algorithm used by a computer! It's the same as the decimal system, but every two into one, so it's just composed of 1 and 0!

Binary numbers are the base of the binary number every 2 digits and are the basic operators; The basis of computer computing is binary, and the binary number of 8 is 00001000.

For example, 73, 73 is first divided by 2 to get 36 and 1, and then 36 is continued to be divided by 2 to get 18 and 0....The binary number of 73 is 1001001.

Binary has only two numbers, i.e. it is every two into one, and computers use binary, which is generally rarely used in life.

Binary numbers have two characteristics: they are composed of two basic characters, 0,1, and the binary number operation rule is every two to one, and the binary number of 3 is 00000011.

A man and a woman are equal to a child, and after a number of years, the child does not get married and has children, which is 1+1=1, and marriage and childbirth are equal to the cycle of repeating and repeating and repeating.

Binary. The carry rule is "every two to one", so a seven-digit binary code can represent a total of 2 to the power of 7 characters, which is 128 characters (0 to 127). The maximum is 1111111, which is 127 in decimal.

Binary system is a number system that is widely used in computing technology. Binary data is a number represented by two numbers, 0 and 1. Its base is 2, the carry rule is "every two into one", and the borrowing rule is "borrow one as two", by the 18th century German mathematical philosophy master Leibniz.

Found. Current computer system.

The binary system used is basically a binary system, and the data is mainly stored in the form of complements in the computer. Binary in computers is a very tiny switch, "on" for 1 and "off" for 0.

The 20th century is known as the third scientific and technological revolution.

One of the important signs of the invention and application of the computer is that the digital computer can only recognize and process by '0''1' symbol string. The mode of operation is binary. 19th century Ireland.

The logician George Bull's thought process on logical propositions translates into a pair of symbols"0''.1''binary is a carry system that is every 2 digits.

is the base operator. Because it uses only two number symbols, it is very simple and convenient and easy to implement electronically.

Representation of binary data.

Binary data also uses position notation, and its bit weight is a power of 2. For example, binary data, every 2 to 1, its weight order is (2). For integers with n digits, binary data with m decimal places is expressed in a weighted coefficient formula, which can be written as:

Binary data can generally be written as:

Example 1102: Binary data is written in the form of weighted coefficients.

Solution: <>

Binary, like hexadecimal and octal, is carried to the power of two.

is in base, and if the lower right corner of the number is 2, the number is in base.

A decimal number 110, the 1 on the hundred digit represents 10 2, that is, 100, the 1 of the ten digit represents 1 10 1, that is, 10, and the 0 of the single digit represents 0 10 0, that is, 0.

A binary number 110, where the high 1 represents a 2 2, i.e., 4, the low 1 represents a 2 1, i.e., 2, and the lowest 0 represents 0 2 0, i.e., 0.

A hexadecimal number 110, where the high 1 represents 1 16 2, i.e., 256, the low 1 represents 1 16 1, i.e., 16, and the lowest 0 represents 0 16 0, i.e., 0.

It can be seen that in the number system, the size of the value represented by the number is not only related to the size of the number itself, but also related to the position of the number, which is called the bit weight of the number.

The calculation is as follows:

Binary. It is a number system widely used in computing technology.

Binary data is a number represented by two numbers, 0 and 1.

Example 1103] Find the sum of 1011(2)+11(2), 1011+11, 1011+11[1].

A special algorithm other than addition, subtraction, and multiplication of binary addition.

Decimal in a computer.

Decimals are usually obtained by multiplying two by rounding them up.

Method: Multiply each binary number by the corresponding power of 2 from right to left, and from left to right after the decimal point.

For example: binary numbers.

Convert to decimal system.

binary) = 1 * 2 0 + 0 * 2 1 + 1 * 2 2 + 1 * 2 3 + 0 * 2 -1 + 1 * 2 -2 = 1 + 0 + 4 + 8 + 0 + decimal).

So to sum up, the general formula is:

Binary) = d*2 0 + c*2 1 + b*2 2 + a*2 3 + e*2 -1 + f*2 -2 + g*2 -3 (decimal).

Features of binary.

1. It is composed of two numbers 0,1, and the binary number operation law is every two into one.

2. The writing of binary numbers is usually marked with base 2 at the bottom right of the number, or B is added after the number.

Difference Between Binary and Decimal:

1. Different uses: binary is mainly used for computer operations, and decimal is mainly used for daily life.

2. Different compositions: binary has only two numbers 0 and 1 to represent it, while decimal is a numerical system composed of ten basic numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.

3. The rules are different: the binary carry rule is "every two into one", and the borrowing rule is "borrow one as two". Whereas, decimal is based on bitsal and decimal digits.

The two principles, that is, all numbers are represented by 10 basic symbols, "full of 10", and the same symbol represents different values in different positions, and the position of the symbol is very important. The basic symbols are ten numbers from 0 to 9. To represent 10 times the ten numbers, move the numbers one place to the right and fill the empty space with a macro 0.

How do you represent a decimal number with a binary number? Represents a one-digit decimal number, which needs to be used at a minimumFour-digit binary.

It's called BCD hail. Implicit.

Because, four-digit binary numbers, there are many permutations and combinations.

Therefore, there are many types of BCD codes.

In the table below, some are listedCommon BCD codes:

Addition: 0+0=0;0+1=1；1+0=1；1+1=10；0 is 1;

Subtraction: 0-0=0, 1-0=1, 1-1=0, disturbance difference 0-1=1;

Multiplication: 0 0=0,1 0=0,0 1=0,1 1=1;

Division: 0 1 = 0, 1 1 = 1.

From the lowest (far right) digit, the digit is multiplied by the weight of the base, and the weight is the digit of 2 minus one by one.

For example, the second digit is the (2-1 times) square of 2, which is 2; The 8th position is 2 (8-1) to the power of 128. Add up all the values.

2 (1-1) represents 2 to the power of 0, which is 1; Other analogies.

For example, binary 1101 is converted to decimal: 1*2(1-1)+0*2(2-1)+1*2(3-1)+1*2(4-1)=1+0+4+8=13

A decimal system, which can be expressed in the decimal system of four pre-paragraph socks and two Hui Burn.

What about two? Let's use eight.
