Although PPL had 64 bits, roughly speaking, it got 12 * 3.322 ~ 40 bits precision.
Due to roundings in decimals, PPL probably had even less precision than 40 bits.

For this Savage test, Python simulation, CAS float precision ~ 42 bits, PPL ~ 37 bits.
StephenG1CMZ Android emulator produce similar numbers.

PPL may eventually be more accurate, but it take huge chain of calculations ...
