二进制数、八进制数、十进制数、十六进制数相互转换方法（Binary, octal, decimal, hexadecimal number conversion method sixteen） There is a formula: binary, octal, decimal number sixteen digits are good in their own base (N-1) square, and the sum of the corresponding decimal number is. A, N=1; ten, N=2 for example..: 1 Party +0*2 2 Party +1*2 110B=1*2 of 0 =0+4+2+0=6D 1 Party +0*8 2 Party +1*8 110Q=1*8 of 0 =64+8+0=72D 1 Party +0*16 2 Party +1*16 110H=1*16 of 0 =256+16+0=272D 2, the number of decimal number to binary, octal, hexadecimal number sixteen The method is the same, namely the integer part with the addition of base for the remaining algorithm, method of fractional part by radical rounding, then the integer and decimal part are spliced into a number as the final result of the conversion. 3, binary conversion into other data types 3-1 binary octal: starting from the decimal point position, the integer part of the left, to the right of each fraction, three bits for a group with an octal numerals, less than three bits with 0 complement, That is a corresponding octal. 010110.001100B=26.14Q Octal to binary and vice versa can. 3-2 binary to decimal: 1 3-3 binary to hexadecimal Sixteen: starting from the decimal point position, the integer part of the decimal part left, right, each four bits for a group with a sixteen hexadecimal numbers, Less than four in 0. That is a corresponding sixteen hexadecimal number.00010100B=26.14H The decimal to hexadecimal To turn the decimal notation, simply divide the binary weights, the remainder remainder first when a digit, second times when the remainder of ten digits, rest and so on, until the divisor is less than the weights, final dividend when the highest digit. A decimal to binary Such as: 55 into binary 2, 55 27 -- 1 bits 13 - 1 second 6 - 1 third 3 - 0 fourth 1 - 1 fifth The final dividend 1 to seventh, which was 110111 Two decimal, octal Such as: 5621 to octal 8, 5621 702 - 5 first (a bit) 87 - 6 second 10 - 7 third 1 - 2 fourth The octal numb
