When a statistic has the output type uint64, the received data can be converted to variable double
type with the following C code:
unsigned long long StatisticData;
DtmResult Result = DtmReadInt64(DtmAddr, CategoryNr,
SettingNr, Index, &StatisticData);
double Statistic = double(StatisticData) / pow(2.0, 64.0);
