Can I use a math function with an input number

Configuration
1

My HA runs my irrigation for my yard. I have an input_number entity that I set to tell the system how long to run each zone. One of my zones is getting too much water and really just needs to run about half as long as the other zones. Can I add a formula to that zone’s script to make it run for half the time as other zones? Something like"input_number/2"?

Here is my current script.

irrigation_run_all_zones:
  sequence:
  - service: switch.turn_on
    target:
      entity_id: switch.master_valve
  - service: switch.turn_on
    target:
      entity_id: switch.zone_1
  - delay:
      minutes: '{{ states(''input_number.irrigation_timer_minutes'') | int }}'
  - service: switch.turn_off
    target:
      entity_id: switch.zone_1
2

Yes, you can do it like this:

  - delay:
      minutes: '{{ (states(''input_number.irrigation_timer_minutes'') | int / 2) | round(0) }}'

The round(0) filter ensures it doesn’t report fractional values like 3.5 minutes (it will be rounded up to 4).
