@simonbyrne @ivanslapnicar Will either of you have a chance to review this or shall I just go ahead and merge?

Dear Simon, dear David,

there is more to this and I will tak a more thorough look soon.

The situation x.hi=0 and x.lo=a!=0 should not happen in a consistent system.

x.lo should always be the lower part of the mantissa, so in this case the number should be stored as x.hi=a, x.lo=0.

Further, presently I get numbers like x.hi=1, x.lo=1e-60, which should not happen for the same reasons.

I will send you some examples soon.

Best wishes, Ivan
