About octal numbers

Eighth numbers represent numbers in octal notation.

In octadecimal numbers, the number is represented by "01234567" with 8 as the base.

An example of conversion in 8 base is as follows. For reference, an example of conversion between binary and hexadecimal 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 8^-1 (1/8), 8^-2 (1/64), 8^-3 (1/512), ... in hexadecimal numbers. If the number after the decimal point cannot be represented by the total of 8^-n, it cannot be completely converted to hexadecimal and an error will occur. In that case, DenCode omits it by adding "..." at the end.
