[SOLVED] How to remove the numbers after the point?

[Flash226 3]

I'm preparing a stage for heating. There is a need for temperature division. As a result, we obtain fractions

I need only 2 numbers after the point. How can I do that?

I'm just starting to make a scene and I have so far only this code

function roundit(num, idp)
  local mult = 10^(idp or 0)
  return math.floor(num * mult + 0.5) / mult
end

 

 

you can then call the function and specify the idp (decimal places you want)

I'm not strong at lua. Only I study. Can you tell where exactly you need to insert a function call?

For example, for 

pices = (gisterezistfloor/35);

 

Debug returns 0.1851428571429

fibaro:debug("tfloor = "..tfloor.."");

 

can be also done like this:

where number between dot and 'f' is number of decimal places. Of course this function also rounds number correctly!

Now I'm faced with another problem.
It is necessary

if tfloor> 28 then tfloor = 28

Any ideas how to do this?

Not quite sure what you mean, but you almost wrote it out yourself...

 

if (tfloor >= 28) then

tfloor = 28

end

 

of course if you put that in a loop you will be in trouble.

Working. I missed the word "end" and that's why I did not work. 

But still I need it to be in a loop

I think this will not work
