Binary Conversion Pro

Binary conversion is a method by which people use symbols to count, including many types of digital conversions. The hexadecimal conversion consists of a digital symbol and two basic factors ("base" and "right"). The cardinality refers to the number of digits used in the carry count system (symbols used to represent "quantity" in the number system). The bit weight refers to the unit value corresponding to each fixed position in the carry system.

Decimal--->binary
For the integer part, the dividend is repeatedly divided by 2, except for the first time, each time divided by 2, the integer part of the previous quotient is taken as the dividend and the remainder of each time is recorded in turn. In addition, the last remaining remainder of the resulting quotient is the highest bit of the binary number sought. For the fractional part, the integer part is successively multiplied by the base 2 and sequentially taken out until the fractional part of the result is zero. Therefore, the law is called "multiplication base method".

Binary--->decimal
The weight of the 0th bit of the binary number is 2 to the power of 0, and the weight of the 1st bit is 2 to the power of 1...

Decimal ---> octal
The method of converting decimal numbers into octal is similar to the method of converting to binary, the only change: the divisor changes from 2 to 8.

Octal--->decimal
Octal is every 8 in 1; octal number uses 0 to 7 to express a number; octal number 0 is 0 to the power of 0, the first weight is 8 to the power of 2, the second The bit weight is 8 to the 2nd power...

Decimal--->hexadecimal
The method of converting decimal numbers into hexadecimal is similar to the method of converting to binary, the only change: the divisor changes from 2 to 16.
