How to use void QTextStream::setRealNumberNotation

tomy

Hi,

I need to use void QTextStream::setRealNumberNotation(RealNumberNotat ion notation). I looked at so-called Docs for it, but there is no example for beginners! (It's here:)

For example:

QString ss;
QTextStream (&ss);
 // here to use it

How to use it please?

Try

ss.setRealNumberNotation(QTextStream::ScientificNotation) or ss.setRealNumberNotation(QTextStream::FixedNotation) or
ss.setRealNumberNotation(QTextStream::SmartNotation)

Thank you. Please have a look at these:

QString s;
QTextStream ss(&s);
ss.setRealNumberNotation(QTextStream::SmartNotation);
ss << 1000000;
result_box -> setText(s);

Here the result is: 1000000
But in this one:

QString s;
double d = 1000000;
QTextStream ss(&s);
ss.setRealNumberNotation(QTextStream::SmartNotation);
ss << d;
result_box -> setText(s);

The result is: 1e+06 !!!

Why? And how to solve it please?

Hi,

You're not using the same types in both code sample. Once you send an integer and next a double. setRealNumberNotation affects float and double, not integers.

OK, thanks.

You're welcome !
