@steve02081504 The resource penalty you mention is miniscule compared to the overall resources required to run YAYA, so I think it is possible to include an implementation that handles extremely large numbers itself.
However, if the process is complex enough to require special demand, such as handling extremely large numbers, I would suggest using a SHIORI implementation in a more general-purpose language such as Python, Ruby, or CSharp, rather than a simple language such as YAYA.
