[Interest] Missing leading zero in exponential format

[Marcel Stegehuis]

Since the upgrade from QT 5.3.1 to 5.7.0 it seems that the string output of the exponential format is missing the leading zero:

Using the code below:
double testValue = 1234.5678;
QString (" <Value>%1</value>\n").arg (testValue, 0, 'E', 2);

I expect:
<Value>1.23E+03</value>
but get:
<Value>1.23E+3</value>

Has anyone a clue if this is intentional behavior or how this could be solved?

Marcel
