Right, thats exactly the problem we have with the our printf and
imagemagick: we always print the next greater representable double,
which in case of 1.0e0 and %.20g is ~1.000000000000000222.
Surely, it would be smarter to only do this for "critical" numbers like
~0.354999, for which we ASSUME that actually 0.355 is meant, but how
would you do that? There are no means to distinguish between 0.355 and
~0.354999 because they both are represented by the same floating-point
number.
Best regards,
Christoph
