How to convert base 5 to base 10
Each base 5 digit is evaluated by its power of 5. The exact value is then repeatedly divided by 10 to produce the destination digits.
value10 = sum(digit x 5position)
For fractional digits, the converter keeps an exact rational numerator and denominator, then generates up to 32 destination digits. An ellipsis marks a repeating or longer expansion.
