Base 30




Base 30 or '''trigesimal''' is a Positional Numeral System using 30 as the Radix . Digit s in this base can be represented using the Hindu-Arabic Numerals 0-9 and the Latin Letters A-T.

From a Mathematical viewpoint, 30 is a convenient choice for a base in that it is divisible by the three smallest Prime Number s (2, 3, and 5) and by their multiples 6, 10, and 15 — many Vulgar Fraction s are easily expressed in base 30. On the other hand, base 30 has poor Radix Economy , and it shares the problem with Base 60 of its radix falling between Twin Prime s, resulting in few Recurring Fraction s having short periods.
