Biquinary, meaning 2-5, is used to refer to a 2-5 code. This can be implemented using a 4 bit binary structure. It is used in the software program Abacus, for example.
The first 10 Decimal numbers with the first 10 Biquinary code numbers are:
| decimal | Biquinary Code |
|---|---|
| 0 | 0100001 |
| 1 | 0100010 |
| 2 | 0100100 |
| 3 | 0101000 |
| 4 | 0110000 |
| 5 | 1000001 |
| 6 | 1000010 |
| 7 | 1000100 |
| 8 | 1001000 |
| 9 | 1010000 |
To encode the Biquinary code use the number 5043210.
At each digit multiple the biquinary number times the number 5043210. This will give you the decimal number.
For example take the numer 0110000. To change this into Decimal:
(5 * 0) + (0 * 1) + (4 * 1) + (3 * 0) + (2 * 0) + (1 * 0) + (0 * 0) = 4
