C Since the initial precision is only float-36, the full D_float
C precision will not be produced in the answer.
C D_Float is exactly like F_Float for the first word. The second
C word consists entirely of lower-order mantissa bits. In our
C example, however, mantissa bits cannot be manufactured from nowhere.
C Float-36 has 26 mantissa bits. F_Float has 24 (first one hidden).
C Therefore, 2 bits, which happen to be 10, will overflow into the
C second word of the D_Float. The remainder of that word
C (vax word N+16) will be 0. Lay this out on the chart, and you will
C see that 20 word n+3 will thus be 200000,,176644, or 17179934116.
