When enlarging an entity (either though an entity card, in the entity list or any other means), the number label on the color temperature slider is not rounded and shows a huge decimal number.

Expected behavior

Proabbly a rounded integer to display.

Open an entity with a color temperature slider using any means and slide the slider, you will notice a huge number will display.
