Rounding template with multiple math

Configuration
1

I having trouble rounding a double math template;

{{ state_attr(config.entity, 'price') | multiply(100.0)-79.03 |  round(2) }}

Without the subtraction it will multiply and round. I tried various ways but the output is always a blank

You are only rounding the number 79.03.

Add some brackets:

{{ ( state_attr(config.entity, 'price') | multiply(100.0)-79.03 ) | round(2) }}

Sorry Tom, but adding the bracket after subtraction gives me a blank as well.
Adding an opening bracket before multiply as well… :confused:

Try this:

{{ ( state_attr(config.entity, 'price')|float * 100 - 79.03 ) | round(2) }}

Nope! Still gives me 15 decimals

I’m surprised you got anything. You are missing quotes around the entity id.

{{ ( state_attr('config.entity', 'price')|float * 100 - 79.03 )|round(2) }}

Unless that is a variable?

Perhaps showing the full context would help.

It’s part of a litecoin view that I have. The latter part is a copy of the ‘secondary’ node, but there I multiply by the amount of coins and substract the start amount in euro’s.

You are still rounding the number:

And there are no closed braces }} after your template. Try this:

  - entity: sensor.crypto_ltc_30_d
        name: 30 Days
        type: custom:template-entity-row
        state: €{{ states(config.entity) | round(2) }}
        secondary: >-
          {{ ( state_attr(config.entity, 'price_change_pct') | float * 100 ) | round(4) }}%
        icon: |
          {% if states(config.entity) | float > 0 %}
             mdi:arrow-up-bold
          {% elif states(config.entity) | float < 0 %}
             mdi:arrow-down-bold
          {% else %}
             mdi:arrow-right-bold
          {% endif %}
       
  - type: markdown
    entity: sensor.crypto_ltc
    content: >
      <h1>€ {{  ( state_attr(config.entity, 'price') | float * 0.99979276 - 125.88 )  | round(2) }}
      </h1> <br> start: €125,88 <br>litecoin: 0,99979276

That did the trick! Thanks
