I'm astonished no one has noticed this before, but in the library
report for the Numeric library, the definition of showFFloat is buggy:
showFFloat Nothing 0.02 ""
goes into an infinite loop. (There is an auxiliary function
'f n s ds' which does not consider the case n < 0).
This suggests that there needs to be a code review of formatRealFloat,
which I have not yet done.
