VAX Floating Point
------------------
Conversion of flonums to floating point is correct, and compatible
with previous assemblers. Rounding is towards zero if the remainder is
exactly half the least significant bit.
`D', `F', `G' and `H' floating point formats are understood.
Immediate floating literals (_e.g._ `S`$6.9') are rendered
correctly. Again, rounding is towards zero in the boundary case.
The `.float' directive produces `f' format numbers. The `.double'
directive produces `d' format numbers.
