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.

52-actual bits, but there is also an impled bit in for an effective mantissa of 53-bits.
The tricky bit[sic] is that in the 64-bit mantissa of the 80-bit animal, there is not an implied bit.
