<h2><a name="BOOST_PP_DEC">#define BOOST_PP_DEC</a>(X)</h2>
|
|
<p>Decrements <code>X</code> expanding to a single token.</p>
|
|
|
|
<p>For example, <code><a href="dec.htm#BOOST_PP_DEC">BOOST_PP_DEC</a>(3)</code> expands to <code>2</code> (a
|
|
single token).</p>
|
|
|
|
<p><a href="dec.htm#BOOST_PP_DEC">BOOST_PP_DEC</a>() uses saturation arithmetic. Decrementing 0 yeilds a 0.</p>
|
|
|
|
<p>Only decimal integer literals in the range [0,<a href="limits.htm#BOOST_PP_LIMIT_MAG">BOOST_PP_LIMIT_MAG</a>] are
|
|
supported.</p>
