added sentence on advantage of bi-quinary encoding on relay based computers.
Line 7:
 
Several human languages, most notably [[Fula language|Fula]] and [[Wolof language|Wolof]] also use biquinary systems. For example, the Fula word for 6, ''jowi e go'o'', literally means ''five [plus] one''. [[Roman numerals]] use a symbolic, rather than positional, bi-quinary base, even though [[Latin]] is completely decimal.
 
One of the advantages of bi-quinary encoding on digital computers is that it must have 2 bits set, one in the binary field and one in the quinary field, and thus there is a built in "checksum" to see if the number is valid or not. Stuck bits happened frequently with computers using mechanical relays.
