Hi

I got a OPTA to read power meter data from a power meter, the one of value is kWh, but the kWh value is too larger to display with decimal point, the real value is 2412421.8, but the value show as 2.4124218e+6 inside things and dashboard.

How to make the value show as decimal point ?
I try to do roundf() and cout << fixed;, it didn't work, and I need the value type able to use is Chart widget.

power0 =2412421.8; / For example

If the value is correct, then change units to MegaWatts. Some context would be helpful, is that number for a residence (unlikely) or a factory, because if t isn't there is an error.
Is is residential and the number is WattHour but you called it kWh forgetting to divide by 1,000.
