<div style="margin-left: 0px;">
The <b>BOOST_PP_GREATER_EQUAL_D</b> macro compares two values for equality or greater magnitude.&nbsp;
It reenters <b>BOOST_PP_WHILE</b> with maximum efficiency.
</div>
<h4>Usage</h4>
<div class="code">
<b>BOOST_PP_GREATER_EQUAL_D</b>(<i>d</i>, <i>x</i>, <i>y</i>)
</div>
<h4>Arguments</h4>
<dl>
<dt>d</dt>
<dd>
The next available <b>BOOST_PP_WHILE</b> iteration.&nbsp;
</dd>
<dt>x</dt>
<dd>
The left operand of the comparison.&nbsp;
Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>.
</dd>
<dt>y</dt>
<dd>
The right operand of the comparison.&nbsp;
Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>.
</dd>
</dl>
<h4>Remarks</h4>
<div>
If <i>x</i> is greater than or equal to <i>y</i>, this macro expands to <i>1</i>.&nbsp;
Otherwise, it expands to <i>0</i>.
</div>
