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.
