QJsonDocument::toJson() generates extra large text.

QJsonDocument::toJson() generate extra large text using double values.
Here is a code:

QJsonObject rootObject;
rootObject.insert("Test",0.05);
qDebug()<<QJsonDocument(rootObject).toJson(QJsonDocument::Compact);

Debug output is always:

I want to get compact output like this:

If I use QJsonArray that contains a lot double values then json output is extreme large.

Is there way to make it compact? If no, than please fix it.
