Thanks for your bug report. It is in fact, as you suspected, due to an error
in the printing rather than the number parsing logic. It worked in 4.1.2
because the number parsing logic in that was "too lenient".
Ironically this and a number of previously fixed bugs with printing floating
point numbers have been caused by the decision to use the C runtime library
to format them (the idea being to avoid re-inventing the wheel - we don't
believe in doing everything in Smalltalk just for the sake of it). Anyway
I've had enough now and I'm going to implement it in Smalltalk for a future
release, but in the meantime I've attached a temporary patch.
Regards
Blair
