A QUINARY number belongs to the numerical place system with 5 as base.

Consequently, whereas the decimal system uses 10 numerals, the quinary one uses only 5 symbols (from 0 to 4).

PROPERTIES

To transform a decimal number into a quinary one you must divide it by 5 repeatedly and write the remainders obtained until the result of the division is 0. The quinary number is obtained by reading the sequence of the remainders in reverse order.

For example:

we transform the decimal number 21.
21:5 =4 remainder 1.
4:5 =0 remainder 4.
We obtain the quinary number 41.
