Hi ☕ 👋 You are not obeying the API contract with this change, i..e people who have passed an int to readTemperature will be in for a surprise. Please add another function, i.e. readTemperatureFloat to retrieve the float value (and may it only be a cast to the result of the other function).

[daneos]

I added the requested changes.

I have to admit though, that I was definitely more surprised to learn it was reading the temperature as int.
My reasoning is the temperature is usually read as float, the device is perfectly capable of reading it with resolution fit for a float value and the documentation says The values returned are signed floats.

Is there a reason for it to be integer?

[aentinger]

I agree the API could have returned a float from the start. The discussion point for me is not what is the better API, but rather how can we honour the API contract established by preceding releases of this library. Now, with an additional function we are not breaking code that is already in use.

LGTM 👍
