turn scientific to fixed

[ramin.lich]

hi all
ok this is my code

void MainWindow::on_pushButton_2_clicked()
{
    QString b;
   float x,y,z;
   x=ui->lineEdit_3->text().toLong();
   y=ui->lineEdit_4->text().toLong();
   z=x*y;
   z=(float)z/100;
   cout<<fixed;
   ui->textBrowser_2->setText(b.setNum(z));
 
}

void MainWindow::on_pushButton_2_clicked()
{
    QString b;
   float x,y,z;
   x=ui->lineEdit_3->text().toLong();
   y=ui->lineEdit_4->text().toLong();
   z=x*y;
   z=(float)z/100;
   cout<<fixed;
   ui->textBrowser_2->setText(b.setNum(z));

}

To copy to clipboard, switch view to plain text mode 

i dont know why still show me scientific format in textBrowser?!?
any help will be grateful.

Try:

ui->textBrowser_2->setText(b.setNum(x*y, 'f'));

ui->textBrowser_2->setText(b.setNum(x*y, 'f'));

thank you so much.
can you also tell me how can i remove float point for example my output is : 500000.000000
in fact my answer is 5000 and 2 zero before point and 6 zero after point is surplus.
thx.

Divide by 100 and floor or round to int.

[ramin.lich]

Thanks again.
i used this but has no effect. ( i mean floor has no effect. divide 100 will makes it better )

b.setNum(floor(x*y/100),'f');

b.setNum(floor(x*y/100),'f');

whats wrong?

How do you know it has no effect? floor() converts a real value to an integer value so as a result you are getting an integer.
