<![CDATA[Something weird]]>When I run case 1, the console output is "True";
But when I run case 2, the console output is "False"

I can't figure it out, somebody help me plz

====== Case 1 =========
QVector <int> av;
int max = 54;

av.append(9);
av.append(6);

if(av.at(0) * av.at(1) == max)
qDebug("True");
else
qDebug("False");

====== Case 2: =========
QVector <double> av;
double max = 0.54;

av.append(0.9);
av.append(0.6);

if(av.at(0) * av.at(1) == max)
qDebug("True");
else
qDebug("False");
