[FIXED] How to avoid qWarning of float values

Issue

I have these following code to set a variable:

void TypeLogVisualization::setGain(double gain)
{
qWarning("Floating point comparison needs context sanity check");
if (qFuzzyCompare(m_gain, gain) || gain < 1.0 || gain > 2.1)
    return;

m_gain = gain;
setPath();
emit gainChanged(m_gain);
}

The variable gain is set in QML File, like the code bellow:

function gainMinus(){
    log.setGain(log.gain-=0.1)
}

function gainPlus(){
    log.setGain(log.gain+=0.1)
}

log is object of a classe who contains "setGain", gain is a QProperty. I really want know how to avoid that warning: Floating point comparison needs context sanity check

Solution

Like everyone said, the only way it's remove that lines
