Lovelace: Button card

Hi all,

I have a custom field which returns the current weather conditions:


      [[[
        …
        …

        var temp = states['sensor.openweathermap_temperature'].state;

        return `<ha-icon 
        icon='${mdi}'
        style='width: 20px; height: 20px; color: var(--text-color-sensor);'>
        </ha-icon>
        <span 
        style='color: var(--text-color-sensor); vertical-align: -1px;'>
        ${w} bei ${temp}°C und einer<br>Niederschlagswahrscheinlichkeit von ${nied}%.
        </span>`
      ]]]

I want the temperature to be displayed with 1 digit instead of 2, but having the same problem as described (and resolved) here.

How can I „translate“ the following solution code for use in my custom field?


{{ '%.2f'|format( states('sensor.outside_table_temperature')|float ) }}
