Howdy!
If I recall correctly (and I'll be checking the references before I do anything), "double precision" and "extended double precision" have different numbers of bits in the exponent. It's not quite that simple to smush the precision down. I think I go from 64 bits of mantissa to 53 bits of mantissa (but don't hold me to precise numbers here). In the end, I should be able to pick the three components apart and Just Do The Math.
yours, Michael
