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.
The Korean finger counting system [[Chisanbop]] uses a bi-quinary system, where each finger represents a one and a thumb represents a five, allowing one to count from 0 to 99 with two hands.
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.
