How to best convert QString with comma to 4byteQstring hex

[erytcg]

Hello I want to convert display text to QString 4 byte hex for example:

QString input ->"119.1"
float ->119.1
int -> 1191
hex int -> 4A7
QString -> "4A7"
QString output -> "04A7" always 4 byte.

bool ok;
    int dec0 = (input.toFloat(&ok))*10;
    //QString dec1 = QString::number(dec0);
    QString c = QString::number(dec0, 16);
    if(c.size()<4) c = QString(4-c.size(), '0')+c;

but when I put 29.3 output = 0124 not 0125.
@edit with .toDouble work great but it's good way?

Casting to int is always rounding down. If you want to round to nearest integer use qRound or add 0.5 before casting.

QString in = "119.1";
QString out  = QString::number(qRound(in.toFloat() * 10.0), 16).toUpper().rightJustified(4, '0');
