# Coordinates / B19

Sub-page of Coordinates

Daniel?: I have been thinking about it and I have a suggestion that in part comes from my experience as a programmer. I call the system B19 (a contraction of Base 19).

Now this takes a bit of a different tack as to where the initial index is (the programming experience coming in) and this may not be to the liking of some, but where for other systems the initial index is 1 or A, the initial index in this system is 0 (which some players may not like) and has a maximum index of I, with the format being (y,x) or yx (which works since every column and row is represented by a single digit).

So what some would call the 1,1 point, in this system would be the 0,0 or 00 or 0 point. Now what is that about you ask? Well, from this column row system there arises a natural numbering system where you can also call a point by a single number rather than as a pair of numbers, with point 0,0 being point 0 and II (aka 18,18 or in a traditional system 19,19) also being called point 360 (= 18*19 + 18).

To summarize B19:

```0 = 0
1 = 1
2 = 2
3 = 3
4 = 4
5 = 5
6 = 6
7 = 7
8 = 8
9 = 9
A = 10
B = 11
C = 12
D = 13
E = 14
F = 15
G = 16
H = 17
I = 18
```

Unfortunately, while this is fairly intuitive for anyone who is well enough versed in computer programming or certain areas of mathematics, it may cause problems for the average player.
