How to convert base 7 to base 10

Each base 7 digit is evaluated by its power of 7. The exact value is then repeatedly divided by 10 to produce the destination digits.

value₁₀ = sum(digit x 7^position)

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.
