|
|
<p><a name="index-VAX-floating-point-1753"></a><a name="index-floating-point_002c-VAX-1754"></a>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><code>D</code>, <code>F</code>, <code>G</code> and <code>H</code> floating point formats
|
||
|
|
are understood.
|
||
|
|
|
||
|
|
<p>Immediate floating literals (<em>e.g.</em> <span class="samp">S`$6.9</span>)
|
||
|
|
are rendered correctly. Again, rounding is towards zero in the
|
||
|
|
boundary case.

<p><a name="index-_0040code_007bfloat_007d-directive_002c-VAX-1755"></a><a name="index-_0040code_007bdouble_007d-directive_002c-VAX-1756"></a>The <code>.float</code> directive produces <code>f</code> format numbers.
|
||
|
|
The <code>.double</code> directive produces <code>d</code> format numbers.
