Domoticz

Would it be possible to increase the number of decimals for the energy tariff? Domoticz rounds it all up to 4 decimals now, while most energy companies use 5 or 6 decimal tariffs (like my current one). This would make energy cost calculations much more accurate. It would also be great if you could set the fixed costs per month and/or day as well. E.g. make it more like your energy company bill(s) are actually calculated by including those factors.
