Convert a double to a QString

Question

I am writing a program in QT. I want to convert a double into a Qstring in C++.

Answer 1

Use QString's number method (docs are here):

double valueAsDouble = 1.2; QString valueAsString = QString::number(valueAsDouble); 

Answer 2

Instead of QString::number() i would use QLocale::toString(), so i can get locale aware group seperatores like german "1.234.567,89".
