    Use the rounding remainder method to do:

    8 2=4 remainder 0

    4 2=2 remainder 0

    2 2=1 remainder 0

    1 2=0 remainder 1

    So the binary of 8 is 100

    15 2=7 remainder 1

    7 2=3 remainder 1

    3 2=1 remainder 1

    1 2=0 remainder 1

    So the binary of 15 is 1111

    Integer part 0 decimal part.

    Integer part 1 Decimal part.

    Integer part 1 Decimal part.

    Integer part 1 Decimal part.

    Integer part 0 decimal part.

    Integer part 0 decimal part.

    Integer part 1 Decimal part.

    So the binary constraint is:

    27 2=13 remainder 1

    13 2=6 remainder 1

    6 2=3 0

    3 2=1 remainder 1

    1 2=0 remainder 1

    Integer part 1 Decimal part.

    Integer part 1 Decimal part 0

    So the binary is.

    So the decimal system of 101101 is 45Among them, 2 5 represents 2 to the 5th power (because the keyboard is not good at typing mathematical formulas, so only this means that when you write, you can change it.)

    Convert the decimal number 268 to a binary number.

    Then convert to a hexadecimal number.

    The calculation is as follows:

    Step 1Convert the decimal number 268 to a binary number.

    Splitting a decimal number into an integer power of 2.

    268 d = 100001100 b

    Step 2to convert the binary number 100001100 to a hexadecimal number.

    From right to left, four digits turn into one.

    10c1 0000 1100 b = 10c h

    Decimal integers are converted to binary integers"Divide by 2 and take the remainder and arrange them in reverse order"Law.

    The specific method is: divide the decimal integer by 2 to get a quotient and remainder; Removing the quotient with 2 will give a quotient and remainder again, and so on until the quotient is less than 1, and then the remainder obtained first will be used as the lower significant digit of the binary number, and the remainder obtained later will be used as the high significant digit of the binary number, and then arranged in turn.

    Principle: As we all know, the base of binary is 2, and the 2 divided by us when we decimalize binary is its cardinality. Speaking of its principle, we have to talk about the concept of position rights.

    The numerical value represented by the digit symbols in a decimal counting system means that the numeric symbol value is multiplied by a constant related to the numeric symbol, which is called the "bit weight".

    The magnitude of the bit weight is based on the cardinality, and the ordinal number of the position of the number sign is an integer power of the exponent. The weights of hundreds, tens, units, and tenths of decimal numbers are 10 to the 2nd power, 10 to the 1st power, 10 to the 0th power, and 10 to the -1st power. A binary number is an n-power of 2.

    If you follow a method similar to changing the base 2, you can change 202 to the base 8, which is also possible.

    The result is 0312

    In 64, if you count how many 64s there are in 202, we get 3, and then 202-64 3=10

    In 8 here, we have to count how many 8s there are in 10, and we get 1, and then 10-8 1=2

    In 1, we need to count how many 1's there are in 2 to get 2

    That is, multiplication, division and subtraction must be calculated once under each column, and since it is occimal, the division result is 0 to 7, not larger.

    Binary looks simple because the division result can only be 0 or 1, so easy that you can ignore its existence, so it looks like just a subtraction.

    Similarly, in the hexadecimal system, the division result of each column may be 0 to 15, which is even more troublesome.

    So the method is the same, but it's only easy to use in binary.

    There is another way.

    It is to first turn the decimal into binary, and then turn the decimal into octal or hexadecimal.

    For example, in 202, binary is 11001010

    From right to left, it is divided into a group of 3 numbers, as 3 base 2 numbers, it is easy to calculate the value of base 10 with your eyes, and the corresponding base 8 is also , and then connected together, the base base of 202 is 312

    Then from right to left into a group of every 4 numbers, as 2 base 2 numbers, it is easy to calculate the decimal value with your eyes is , corresponding to the hexadecimal is c, a, and then connected together, the hexadecimal system of 202 is ca

    Decimal decimal is converted to n: multiply by n, round up sequentially.

    2= Take 1

    A decimal decimal does not necessarily translate to a binary decimal exactly, approximately 7 digits.

    The base system is converted to the decimal system, and the bitwise weight.

    0 is 7 digits 0*2 7+

    1 is a 6-bit 1*2 6+

    0 is 5 digits 0*2 5+

    1 is 4 digits ··

    1 is 3 digits.

    0 is 2 digits.

    1 is 1 bit.

    1 is 0 digits 1*2 0

    Use the "divide by 2 remainder" algorithm:

    126 2 quotient 63 remainder 0

    63 2 quotient 31 remainder 1

    31 2 quotient 15 remainder 1

    15 2 quotient 7 remainder 1

    7 2 quotient 3 remainder 1

    3 2 Quotient 1 Remainder 1

    1 2 quotient 0 remainder 1

    Composition binary number: 111 1110

    2 to 10: 1011 (binary) = 1x2x2x2 + 0x2x2 + 1x2 + 1 = 11 (decimal), binary addition: 1101 + 1011 = 11000, decimal to binary:

    Divide the decimal number by 2 to take the remainder, and then divide the quotient by 2 and take the remainder, until the remaining 1 is divided by 2 and the remainder is 1 quotient 0, and then the remainder is reversed to row the binary number, remember that there is no remainder during the period to make up the remainder with 0, and the binary is reduced by two times (this sentence is a wrong statement, the narrowing is the fraction, and the expansion is the multiple, I will treat you as a shrinking halve): 1101x1 2=(, hexadecimal to binary: each bit of the hexadecimal number can be converted to 4-digit binary:

    1e (hexadecimal) = 0001

    1101, of which 1 against 0001 and e against 1101

    So: 300d = 12c h

    So: 300d = 100101100 b binary to decimal, first write the bit weight of the bit on each digit, that is, the first bit on the right is 2 to the power of 0, the second bit from the right is the 1st power of 2, and so on, into the following figure; Then multiply the value on each bit by the corresponding bit weight, and finally add it up.

    Binary to hexadecimal, binary numbers from right to left every 4 digits in a group, see the figure below;

    I've detailed one of these examples in the various types above.
