Bitwise Problem [Solved - a typo]

[kendavistoo]

I ran the following snippet:

quint32 a1, a2, zz;

a1 = 0x0000AB8F;
a2 = 0x00FCE888;

zz = a2 & a1; //Bitwise AND

QString astr1 = QString("%1").arg(a1, 16, 16, QLatin1Char('0') );
cout << "\n a1 "<<astr1.toUpper().toStdString() << " "<<a1;

QString astr2 = QString("%1").arg(a2, 16, 16, QLatin1Char('0') );
cout << "\n a2 "<<astr2.toUpper().toStdString() << " "<<a2;

QString zzstr = QString("%1").arg(zz, 16, 16, QLatin1Char('0') );
cout << "\n zz "<<zzstr.toUpper().toStdString() << " "<<zz;

cout << "\n ";

QString mystr1;
mystr1.setNum(a1,2);
QString urstr1 = QString("%1").arg(mystr1, 32, '0' );
cout << "\n a1 "<< urstr1.toStdString();

QString mystr2;
mystr2.setNum(a2,2);
QString urstr2 = QString("%1").arg(mystr2, 32, '0' );
cout << "\n a2 "<< urstr2.toStdString();

QString mystrz;
mystrz.setNum(a1,2);
QString urstrz = QString("%1").arg(mystrz, 32, '0' );
cout << "\n zz "<< urstrz.toStdString();

cout << "\n ";

and got this as a result:

a1 000000000000AB8F 43919
a2 0000000000FCE888 16574600
zz 000000000000A888 43144

a1 00000000000000001010101110001111
a2 00000000111111001110100010001000
zz 00000000000000001010101110001111
This appears to be incorrect. What am I doing wrong?
