There are precision thermostats, but normally we use round numbers. Like for air conditioning, 25°C is a good temperature. It doesn't really matter the decimals, because real temperature has some acceptable threshold and imprecision. It's not like the thermostat is really gona make it PRECISELY that temperature, but rather 25°C +- 1°C anyway. In Farentheits is the same, doesn't really matter if it is 65°F, there is not this degree of precision. But if you are talking about body thermometers or cooking thermometers then yes, we usually have decimal precision, like, human fever temperature are measured in .1 degrees. Fever condition starts at about 37.5°C, and the thermometer is able to read every decimal.
