I have flashed the slug to SlugOS (still big endian) and got gdb on it.
It appears that the issue is not so much the fpu or floating point but
with the FloatStr, StrToFloat etc conversions which seem to get stuck in
system.str.
I have tried to chase the system.str function but got lost in the {$i
xxxx} includes and header files :(
Any hints on how to debug this further?Terry here is the session...
