Qt : conversion in binary, decimal and hex
This is a basic article for Qt : conversion in binary, decimal and hex. From this tutorial, you can know how Qt : conversion in binary, decimal and hex. Qt have rich class to convert from a data from one data type to other. From this tutorial, I am use QString class to convert a number to binary, decimal and hex number.
Please check this main.cpp code :

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
#include <QCoreApplication> #include <QDebug> #include <QString> int main(int argc, char *argv[]) { QCoreApplication a(argc, argv); bool ok; QString str = "FF"; qDebug()<<"Input (HEX) = " << str; int iVal = str.toInt(&ok,16); QString binnumber = str.setNum(iVal, 2); qDebug()<<"Convert to Int = " << QString::number(iVal); qDebug()<<"Convert to Binary = " << binnumber; return (0); } |
This is contents for the *.pro file :
