This is almost not worth mentioning but since it is a bug, I'll mention it.
I put 98.0 in the 'F field of PE. Press the 'F' to change it to 'C'. Then press the 'C' to get back to 'F' (let's say you clicked on the 'F' originally by accident or something). The temp will now read 98.1 'F.
It must be a truncation error in the calculation that rounds up.
