Integer to price conversion using Qlocate

Question

How can I use QLocate to convert integer into standard Brazilian price form (without rounding up the figures)?

Code:

QString n1 = "1.020,50";
QString n2 = "10,33";

int  valor1 = n1.replace(".","").replace(",","").toInt();
int  valor2 = n2.replace(".","").replace(",","").toInt();

int resultado_int = (valor1 + valor2);
qDebug() << resultado_int; //correto sem arredondar 100383

//converter
QLocale loc = QLocale::system();
QLocale brasil(QLocale::Portuguese);
loc.setNumberOptions(brasil.numberOptions());
QLocale::setDefault(loc);
qDebug() << brasil.toString(resultado_int); //erro return = "103.083" 

Answer 1

This is because you have removed the ',' and the '.' to make an integer. But when you go to print the final amount you do not return with the part of the cents and conversion believes it is 103,083 real and 0 cents.

To solve this by converting to float only at the end:

QString n1 = "11.020,50";
QString n2 = "10,33";

int  valor1 = n1.replace(".","").replace(",","").toInt();
int  valor2 = n2.replace(".","").replace(",","").toInt();

int resultado_int = (valor1 + valor2);
qDebug() << resultado_int; //correto sem arredondar 100383

//converter
QLocale loc = QLocale::system();
QLocale brasil(QLocale::Portuguese);
loc.setNumberOptions(brasil.numberOptions());
QLocale::setDefault(loc);
qDebug() << brasil.toString(resultado_int * 0.01, 'f', 2); // Retorna 11.030,83"
