Energy add more decimals to rate

My utility bill rate is to the fourth decimal place. To make cost tracking more accurate it would be great to add more decimals to the fixed rate in the settings.

My gas provider has rates out to 5 decimal places. I use input_number at the moment, so yes would be nice to increase this.

yes, this needs to be addressed. Our energy price is 0.1439€/kWh, but can only input 0.14 or 0.15 … :confused:
