|
|
The <b>BOOST_PP_GREATER_EQUAL_D</b> macro compares two values for equality or greater magnitude.
|
|
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.
|
|
</dd>
|
|
<dt>x</dt>
|
|
<dd>
|
|
The left operand of the comparison.
|
|
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.
|
|
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>.
|
|
Otherwise, it expands to <i>0</i>.
|
|
