Send float to script using parameters

How do I send a float to a script?

Here’s my code:

sensor:
  - platform: dallas_temp
    id: livingroomtemp
    name: "Livingroom Temperature"
    update_interval: 10sec
    on_value:
      then:
        - logger.log:
            format: "Sensor component - %f"
            args: id(livingroomtemp).state
        - script.execute:
            id: settemp
            tm: id(livingroomtemp).state

script:
  - id: settemp
    parameters:
      tm: float
    then:
      - logger.log:
          format: "Script - %f"
          args: tm

The logger output is:

[15:50:01][D][dallas.temp.sensor:054]: 'Livingroom Temperature': Got Temperature=20.8°C
[15:50:01][D][sensor:093]: 'Livingroom Temperature': Sending state 20.75000 °C with 1 decimals of accuracy
[15:50:01][D][main:344]: Sensor component - 20.750000
[15:50:01][D][main:367]: Script - nan

The temperature is reported correctly from the sensor component code. Why is the temperature reported as “nan” from the script? Thank you.

I think I figured it out:

        - script.execute:
            id: settemp
            tm: !lambda return id(livingroomtemp).state;
