function() in the scheduler

[SoftVienka]

Hello
Is it possible to use the round() function in the scheduler?

Write entity RAM float (17.25) to entity RAM as int (17)

example:
Command: custom/interval
Value: (x > 2 && x < 10) ? custom/interval_1 : custom/interval

interval_1 is a float and I want it to be stored as an int into interval

when I write round(custom/interval1) then npr: round17.25 is written into the interval

@MichaelDvP we could set a value type to the RAM custom entity. Now it's fixed as DeviceValueType::STRING in WebCustomEntity::update(). And do the conversion in the C++ code to BOOL INT STRING

Adding functions to the command/scheduler shunting Yard will be a big change. This is what is supported today: https://emsesp.org/Configuring/#scheduling-actions

I think adding a few unary functions to shunting yard is not so much work, I think round, int, abs are usefull. Maybe also sqrt. I think trigonometric, logarithmic and hyperbolic function are rarly used in heating, will skip them. I'll make a change to my dev next days and a PR after testing.
The ram values are used for commands which always expects const char*arguments, also shunting yard works with strings. But we never add uom to strings, maybe it's nice to show a uom to ram values?

PS: round should work now in https://github.com/MichaelDvP/EMS-ESP32/releases/tag/latest

nice! I created a new issue for this, for 3.7.0

round() works, it immediately looks prettier

just a side note:
In the dashboard, every other row could be highlighted, as it is in devices.

Thank you
