Lets assume you are too lazy to implement the
recursive Schoenhage algorithm for toString(),
as is found in Java BigInteger.

Are there BigIntegers based on BCD coding.
I guess they could also do FFT multiplication?

Interestingly IBM, also for their new POWER9,
still provides BCD coding support.

Something open source or benchmark through
OpenPower Foundation?

How fast 9^(9^9) on summit?
