Show negative numbers?

[petterca]

I'm currently using a battery-state-card to visualize a range of temperatures in my Home Assistant setup. While I'm quite satisfied with the card overall, I've encountered an issue where it seems unable to display negative temperature values. Could you please advise on how I can configure the card to correctly show negative temperatures?
