About hexadecimal numbers

Hexadecimal represents numbers in hexadecimal notation.

In hexadecimal, the number is represented by "0123456789ABCDEF" with 16 as the base. Decimal numbers 0 to 9 are represented by 0 to 9 even in hexadecimal numbers, and 10 to 15 are represented by A to F.

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

Decimal	Binary	Octal	Hexadecimal
0	0	0	0
1	1	1	1
2	10	2	2
7	111	7	7
8	1000	10	8
9	1001	11	9
10	1010	12	A
15	1111	17	F
16	10000	20	10
17	10001	21	11

Also, numbers after the decimal point are converted as 16^-1 (1/16), 16^-2 (1/256), 16^-3 (1/4096), ... in hexadecimal numbers. If the number after the decimal point cannot be represented by the total of 16^-n, it cannot be completely converted to hexadecimal and an error will occur. In that case, DenCode omits it by adding "..." at the end.
