How to create fixed decimals in a sensor

Configuration
1

In this forum I did check how to create fixed decimals at a sensor value.
I did found the format extension and tried that like:

    magnetron_energie_today_euro:
      friendly_name: "Kosten magnetron vandaag"
      unit_of_measurement: "€"
      icon_template: "mdi:currency-eur"
      value_template: "{{ '{:.2f}'.format(((states('sensor.magnetron_energie_daily') | float) * (states('sensor.dsmr_day_consumption_energy_supplier_price_electricity_delivered_1') | float)) | round(2)) }}"

Using: ‘{:.2f}’.format for formatting two decimals
But it stil gives:

What am I doing wrong?
Thanks for the help

If paste it into templates do you see what you want

Off top head in your profile there a number format setting

Thanks for your answer. I didn’t think about that.
There it shows indeed a template of 2 decimals:

But in the card not

Which card are you using? Doesn’t look like plain “entities”.
It might itself do a conversion to float, which would make your forcing to 2 decimals useless.

My Yaml code looks like this:

It’s about the entities

I’m pretty sure the number gets converted to float, maybe at localization level.
You might want to try playing with those settings.

Thanks again. I will try

I tried. to change as you mentioned but no change unfortunately.
The strang part is that if not using the format template it shows 1 digit in result:

image1585×471 42.2 KB

and using format template it says two digits in result:

image1685×503 43.3 KB

but in the card at frontend it is not showing two digits:

image722×659 23.8 KB

That is what i’m confused about

Change number format in user part as you mentioned is not effect the result also
