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.
