|

|
|
<p>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.
|
||
|
|
</p>
|
||
|
|
<p><code>D</code>, <code>F</code>, <code>G</code> and <code>H</code> floating point formats
|
||
|
|
are understood.
|
||
|
|
</p>
|
||
|
|
<p>Immediate floating literals (<em>e.g.</em> ‘<samp>S`$6.9</samp>’)
|
||
|
|
are rendered correctly. Again, rounding is towards zero in the
|
||
|
|
boundary case.

||
|

|
<p>The <code>.float</code> directive produces <code>f</code> format numbers.
|
||
|
|
The <code>.double</code> directive produces <code>d</code> format numbers.
