[Qt-interest] QString::toInt

[Scott Aron Bloom]

To put it more clearly...

 

The default value for base is 10, not 0.

 

If you want it to "auto detect" you must EXPLICTLY set base to 0

 

    qDebug() << QString( "0xFF" ).toInt( NULL, 0 );

 

 

Works like a charm

Hi,

In the documentation http://doc.qt.nokia.com/latest/qstring.html#toInt
,it is mentioned 

"If base is 0, the C language convention is used: If the string begins
with "0x", base 16 is used; if the string begins with "0", base 8 is
used; otherwise, base 10 is used."

I understand from the above sentence that if the string begins with "0x"
then base 16 is used implicitly while if the string begins with 0 base 8
is used implicitly.

However this is not the case.

 

QString str2 = "0xFF";

qDebug()<<str2.toInt(); //0 zero

 

QString str3 = "0789";

qDebug()<<str3.toInt(); //789

 

bool ok;
qDebug()<<str2.toInt(&ok, 16);//255

 

               

Any clarification what does above sentence mean?

 

Thanks,

Nandita
