One thing that one has to watch out for is a big-endian IBM long double

I've tried to handle that right, i.e. on

One reason for that is that neither conversion is lossless, neither format
is a subset or superset of

The lack of bug reports since the conversion feature was introduced in
2006, more than 15 years ago, tells us somethi
