<h4 class="subsection">9.48.2 VAX Floating Point</h4>
<p><a name="index-VAX-floating-point-2344"></a><a name="index-floating-point_002c-VAX-2345"></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> ‘<samp><span class="samp">S`$6.9</span></samp>’)
are rendered correctly. Again, rounding is towards zero in the
boundary case.
<p><a name="index-g_t_0040code_007bfloat_007d-directive_002c-VAX-2346"></a><a name="index-g_t_0040code_007bdouble_007d-directive_002c-VAX-2347"></a>The <code>.float</code> directive produces <code>f</code> format numbers.
The <code>.double</code> directive produces <code>d</code> format numbers.
