scanf() cand read what printf() produced: NaNs and Inf

Hi,

printf() generate special tokens when outputing float/doubles that are
not numbers (NaN) or are infinity (Inf).
However, scanf() can't read those tokens. Is this deliberate? Is there a
standard for these cases? If I contribute with a patch to correct the
problem will it (in principle) be accepted?

Thanks,
Joao
