About binary numbers

Binary numbers represent numbers in binary notation.

In binary, the number is represented by "01" with 2 as the base.

An example of conversion in binary is as follows. For reference, an example of conversion between octal and hexadecimal numbers is also provided.

17100012111

Also, numbers after the decimal point are converted as 2-1 (1/2), 2-2 (1/4), 2-3 (1/8), ... in hexadecimal numbers. If the number after the decimal point cannot be represented by the total of 2-n, it cannot be completely converted to hexadecimal and an error will occur. In that case, DenCode omits it by adding "..." at the end.
