yep, that was coming to my mind, too.
even c64 basic interpreter could do floating-point arithmetic - 6510 processor alone wasn`t able to do that. it was all done in
maybe there exists a suitable c-library?
is a start ?
so - find an apropriate c-library and probably just use that for your plugin....
(sorry if this is a wrong hint - i`m no real programmer - but perhaps this gives an idea....)
as far as i remember linux-kernel on 386 processors without fpu was able to do floating-point "emulation", too.
