Rather than mess with the bignum implementation, Add a "CellSize"
configuration for imonlcd, and write some code to scale the font to the
CellSize specified. So, between "Size" and "CellSize", you can basically
create a pseudo 1 line LCD with a big character size. It would be
transparent to LCDproc and you would not need to mess with legacy support for
bignum. Check out the sed1330, which according to the docs, MIGHT do
something like this (but as I recall, CellSize might not be totally
Anyway, bignum is not the right way to do what you want.
