The binary number 110000 is converted into hexadecimal number 30H. Binary and hexadecimal have 4 bits corresponding to one bit. 110000 should be regarded as 0011 0000. Among them, 0011 corresponds to 3 in hexadecimal, and 0000 is still 0. Therefore, the answer is 30H (hex flag).
Conversion between binary numbers and other base numbers:
(1) Binary to decimal conversion: multiply the base number by the weight, and then add it to simplify the operation You can leave out items whose digits are 0 (because 0 times other numbers that are not 0 are all 0). The same goes for the decimal part, but with less precision.
(2) Convert binary to octal: Use the "three-digit unification method" (which is to group every three digits to the left and right with the decimal point as the center, and add 0 for any shortage). This way you can easily to convert. Example: Convert the binary number (11100101.11101011)2 into an octal number. (11100101.11101011)2=(345.353)8
(3) Binary to hexadecimal conversion: The "four-digit unification method" is used. The integer part starts from the low bit, and every four binary digits are one. Group, if there are less than four digits in the end, add 0 to the high digits until the four digits are completed, or you may not add 0; the decimal part starts from the high digits, and each four-digit binary number is a group. If there are less than four digits in the end, 0 must be added to the low digits. Complete the four digits, replace them with the corresponding hexadecimal numbers, and then write the corresponding hexadecimal numbers in order. Example: Convert the binary number (10011111011.11101100)2 into a hexadecimal number. (10011111011.11101100)2=(4FB.EC)16
