Number

When dragons on Dracca trade, they use a octal system.

Numbers

To write octal numbers, group the figures by four, and put a space between each group. To read the number, simply read each figure of each group. Add a"o" to the end of the last figure of every group, except the last group. Put a "o" at the end of the last figure of the last group.

Writing octal with decimal figures

You can write octal numbers using decimal numbers (0, 1, 2… 7), but you should always keep the figures grouping. Group the decimal figures in sets of four, and prepend "0" to the first group. If the first group already has four decimal digits, then put a group of "0" before. For instance, don't write 17 for unsepti, and write 0017 instead. To write the decimal number 1000, that is 1750 in octal, prepend it with a group of zeros, so you write 0000 1750 for "one thousand".
