Вывод в label информации о весе, с тензодатчика.
Добрый вечер. Пробую делать весы на Ардуино. Вес из ардуино, получаю через COM порт, в граммах. Как вывести значения в label с маской "0.000". Чтобы нули всегда были впереди?

Добрый вечер.
У меня вес в граммах, int, вот мне надо выводить что то типа "0.054 гр." или "0.158 гр", а у меня сейчас "54 гр" "158 гр".
Да я вас понял.
setText(QString::number( 54 / 1000, 'f', 3 ) + QString(" гр."));Спасибо. Я все понял. А я то искал через QString.arg или sprintf(). Но все как всегда просто.
