Answers to Questions (FAQ)
What are babylonian numbers? (Definition)
In mesopotamian/babylonian number system, our current number system, called hindu-arabic (0,1,2,3,4,5,6,7,8,9) did not exist. Numbers are written in a cuneiform style with | (pipe or nail) and < (corner wedge or bracket), written in base 60.
How to write babylonian numbers?
Each vertical bar | equals a unit and each < equals a tenth. The change of power of sixty (60 ^ 1 = 60, 60 ^ 2 = 3600, 30 ^ 3 = 216000, etc.) is represented by a space.
Example: 23 is written with 2 tenths and 3 units so <<||| or .png)
.png)
Example: 61 is written 1 sixtieth and 1 unit as | | or .png)
(with a space separator)
dCode uses the recent system (from the 3rd century civilization in Babylon) which introduce the writing or 0 (before the concept of zero did not exist, it was replace by an ambiguous empty space).
Since Unicode 5 (2006) cuneiform symbols can be represented on compatible browsers, here is the table of characters used by dCode:
| π | 1 | π | 2 | π | 3 | π | 4 | π | 5 | π | 6 | π | 7 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| π | 8 | π | 9 | π | 10 | π | 20 | π | 30 | π | 40 | π | 50 |
How to convert babylonian numbers?
Converting is easy by counting symbols and considering it in base 60 to get numbers into classical Hindu-Arabic notation.
Example: <<||| is 2 < and 3 | so $ 2 \times 10 + 3 \times 1 = 23 $
Example: | | (note the space) is 1 | and then 1 | so $ 1 \times 60 + 1 = 61 $
How to convert from base 10 to base 60?
To convert a number $ n $ from base $ 10 $ to base $ b=60 $ apply the algorithm:
// pseudo-code
q[0] = n
i = 0
while (q[i] > 0) {
r[i] = q[i] mod 60
q[i+1] = q[i] div 60
i = i+1
}
return q
Example: $$ q_0 = 100 \\ r_0 = 100 \mbox{ mod } 60 = 40 \;\;\; q_1 = 100 \mbox{ div } 60 = 1 \\ r_1 = 1 \mbox{ mod } 60 = 1 \;\;\; q_2 = 0 \\ \Rightarrow \{1,0,0\}_{(10)} = \{1, 40\}_{(60)} $$
