How to convert numbers to local currency format?
-
@SGaist I did not do this.
Where in the code should I put this "import"?
I tried to put in the .pro file but it didn't work. QT did not recognize this command.

At the top of your .qml file as explained here in Qt's documentation.

@SGaist I forgot to say that I am programming in C ++. I think the .qml file is not accepted here, right?

Your examples above ar qml, now you're telling us you're trying to compile qml code in C++??

@Christian-Ehrlicher Excuse me. My mistake. I'm new to QT.
I think I looked in the wrong part of the documentation.
The above example was copied from the QT documentation.

What is the method for converting numbers to local currency so that these numbers, even with currency formatting, can be used in mathematical expressions (sum, multiplication, etc.)?
-
Use QLocale

as @Christian-Ehrlicher say, you have to used QLocale, like this:
auto german = QLocale("de_DE"); double value = 1234.56; qDebug() << german.toString(value, 'f', 2); -
Hello friends.
I am trying to convert typed numbers in a line edit to local currency format.
I tried as in the QT documentation, but it didn't work. The compiler does not recognize NUMBER QMT TYPE.
It also does not recognize the variable type VAR, as shown in the example QT documentation.
I copied below what is in the documentation:
Method Documentation
string fromLocaleString(locale, number)
Returns a Number by parsing number using the conventions of the supplied locale.
If locale is not supplied the default locale will be used.
For example, using the German locale:Method Documentation
string fromLocaleString(locale, number)
Returns a Number by parsing number using the conventions of the supplied locale.
If locale is not supplied the default locale will be used.
For example, using the German locale:<code>
var german = Qt.locale("de_DE");
var d;
d = Number.fromLocaleString(german, "1234,56") // d == 1234.56
d = Number.fromLocaleString(german, "1.234,56") // d == 1234.56
d = Number.fromLocaleString(german, "1234.56") // throws exception
d = Number.fromLocaleString(german, "1.234") // d == 1234.0<code>
Do I need to do some INCLUDE? Is this method obsolete? What is the most practical method to do this?

I am trying to convert typed numbers in a line edit to local currency format.
double num = lineEdit->locale().toDouble(lineEdit->text()); -

Thank you.
But I only have one more small question:
I read from the QT documentation that there is a way for QLocale to include the local currency symbol in the formatted number. Although I read, I couldn't understand how to do that.
After your tip, I was able to format the numbers to the local currency, but I'm concatenating the Brazilian currency symbol next to the number.
How can I enter the currency symbol through QLocale?
