linux - Qt 4.8.2
Hello,
I'm trying to convert binary strings to decimal.
Getting an error only on 32 bit binary strings. I've marked where I think the error could be, but not shore.
1, 2, 4, 8, & 16 splits are fine.
Perhaps some kind soul can explain where I'm going wrong.
Regards
Maybe thia question does not belong on this forum, feel free to delete.

int split = 32; // 1, 2, 4, 8, 16, 32 byte data split
QString data
= readEeprom

);
int dl = data.length();
if (dl %split != 0) {
qDebug() << "Data length is not wholly divisible by split - (" << split << ")";
return; //exit(1);
}
qDebug() << "data - " << data << "-" << dl << "bytes -" << "split =" << split << endl;
