how to convert hexadecimal to decimal

Explanation: mutual conversion of binary, octal, decimal, and hexadecimal values: in addition to the remainder of 2, the integers are arranged in reverse order, that is, each time an integer is divided by 2, and the remainder is the number on the right, the quotient is divided by 2, and the remainder is the number of the previous right. this step continues until the quotient is 0, and the conversion between

. In the following course about hexadecimal conversion, you can find this point. 　6.2 convert binary number to decimal number 6.2.1 convert to decimal number 0th bits in binary are 0 to the power of 2, and 1st bits are 1 to the power of 2 ...... Therefore, there is a binary

//int itemp = Convert.ToInt32 (Decimalspart[i]. ToString ()); thetemp =Integerpart[i]; the //determine if decimalspart[i] is a letter + if(Char. Isletter (temp)) - { the if(Char. Isupper (temp))Bayi { thetemp = Convert.tochar (Convert.ToInt32 (temp) + +); the - } - //if it's a letter, convert it to lowercase

topic requires the retention of 4 decimal places, the result is: 0.736d≈0.1011b or 0.736d≈0.1100b.　　Six, non-ten numbers converted into decimal numbersSince any number can be expanded by weight, it is easy to convert a non-decimal number to the corresponding decimal number.

relationship, that is, 23=8,24=16, while octal and hex are used in this Derived from the relationship, that is, a three-bit binary representation of an octal, with a four-bit binary representation of a hexadecimal number. Next, remember 4 numbers 8, 4, 2, 1 (23=8, 22=4, 21=2, 20=1). Now let's practice the conversion between binary and octal. (1) binary into octal Methods: Take the Triad method, that is, from the
