<H3>BOOST_WARN_EQUAL( left, right )<BR>
BOOST_CHECK_EQUAL( left, right )<BR>
BOOST_REQUIRE_EQUAL( left, right )</H3>
<P class="first-line-indented">Check performed by these tools is the same as
the one performed by <A href="BOOST_CHECK.html"> BOOST_&lt;level&gt;</A>( <I>left</I> ==
<I>right</I> ). Use these tools if you want to see the mismatched runtime
values. Note that it most probably bad idea to use these tools to compare
floating point values. Use <A href="BOOST_CHECK_CLOSE.html">BOOST_&lt;level&gt;_CLOSE</A> or
<A href="BOOST_CHECK_CLOSE.html">BOOST_&lt;level&gt;_CLOSE_FRACTION </A>tools
instead.</P>
<P class="first-line-indented"> The first parameter is the <I>left</I> compared
value. The second parameter is the <I>right</I> compared value. Parameters
are not required to be of the same type. But there should exist comparison
operator for <I>left</I> and <I>right</I> type (this may involve
implicit conversions).</P>
