Description of problem:
When a temperature sensor with two decimal values, the values are rounded to a one decimal value.
If the sensor reports values above .95 (e.g. 18.96 °C) the card shows is as 18.10 instead of 19.0.

Ah jeez, this is still an issue.
It's not limited to two decimal places either; 18.9 is rounded to 18.5 and 19.1 is rounded to 19.5.
