How to convert base 8 to base 16

Each octal digit is evaluated by its power of 8. The exact value is then repeatedly divided by 16 to produce the destination digits.

value₁₀ = sum(digit x 8^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.
