What is the difference between value = QString::number(jval.toDouble()) and value.setNum(jval.toDouble(), 'f', 0) ?

The original method would turn the double value into a scientific count

eg:

QString::number(2147483647) output  2.14748e+09
value.setNum(2147483647, 'f', 0) output 2147483647

I just want him to print it as it is, not in scientific notation

Why are you removing the decimal ? This looks like a data degradation to me. I tested your code and value.setNum(21.474836.47, 'f', 0) output 21.
