Reports floating-point values that are being compared using the <code>==</code> or <code>!=</code> operator.
<p>Floating-point values are inherently inaccurate, and comparing them for exact equality is seldom the desired semantics.</p>
<p>This inspection ignores comparisons with zero and infinity literals.</p>
<p><b>Example:</b>
<pre><code>
void m(double d1, double d2) {
if (d1 == d2) {}
}
</code></pre>
