Very interesting. Probably special C directive (unless something like
'extended float' is some kind of C (unofficial) standard. I'll check
x86 architecture reference.

Incidently, if I recall, the arguments against 'very high precision'
was coming from scientists (e.g. those dealing with quantum mechanics
issues) rather than from programmers. The main argument was that the
measuring tools' precision is soo well below 53bit precision available
as 'C double' that using anything higher than that will mistakenly
create the impression of 'very high precision of the experiment' - but
this is just it - *mistakenly*.
