Yes, that's _a_ requirement. Not _the_ requirement.

It's like marketing saying we need a 32bit ADC resolution.
Yes, we can do that. No, the ADC will not deliver 32bit
and it doesn't need to either.

Without knowing what the application is, it is very hard
to say whether the 0.1 degree is just a number out of thin
air or really a requirement of the system.
