Actually not quite as easy as I thought. Do we also want the float and
ld versions? And how are they supposed to behave on inf/nan? I think
an optimal implementation would be something like:
if (isnormal(x.d)) return x.rep = (x.rep&mask|exp_0), x.d;
else return scalbn(x, -ilogb(x));
and then just always using scalbnl for ld so as not to introduce more
ld-format-specific code just for legacy purposes.
Anyone up for submitting a patch?
