Daily? No. Never. I’d actually think it weird if an app or person told me the weather temperature with decimal places. The only place I’d expect to see decimals is body temperature which is not daily and not something you really think about.

I grew up using Celsius but had a thermostat in Farenheit for long enough to get accustomed to them both, at least when it comes to comfortable living temperature ranges. I find they both work fine in that range, but (likely because I grew up with it) find Celsius much more intuitive when it comes to more extreme temperatures.

As said elsewhere, every ten degrees more or less marks different weather ranges for what I can expect to feel and wear that day.
