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.
