, just like is also 25.
To convert a number (integer, in decimal writing), start by writing it in base 25 (see writing in base N), then substitute each value (between 0 and 24) by the corresponding D'ni symbol.
Example: $ 123_{(10)} = 4 \times 25 + 23 = [4,23]_{(25)} $ i.e.
How to convert a D'ni number into decimal?
The conversion begins by replacing each symbol of the base 25 D'ni by its value (between 0 and 24) then processing the number obtained as written in base 25 in order to convert it to base 10 (decimal).
Example: matches the digits $ 4 $ and $ 23 $, i.e. $ [4,23]_{(25)} $ hence the conversion calculation $ 4 \times 25 + 23 = 123 $ in base 10.
How to recognize D'ni digits? (Identification)
The D'ni numeric symbols are square and have inside either lines (horizontal, vertical or diagonal) or arcs of circles connecting 2 adjacent corners.
Any references to Myst and Riven video games are clues.
