    Question How to send the output(say average) to a lineEdit?

    Hi everyone. I am new to qt programming.
    I want to compute the average and display the output using a lineEdit.
    I used

    ui->lineEdit->setText(QString::number(avg));
    This displays the output without decimals. How to display float in lineEdit?

    Thanks in advance..

    There are several overloaded QString::number() variants.
    have a looks at this one:

    Do you write clean code? - if you are TDD'ing then maybe, if not, your not writing clean code.
