labeling by arcade ||| etiquetar con arcade

[JavierCMartínezPrieto]

good afternoon, everyone,
I have a webmap where I represent kilometer points every meter, I would like to be able to label those P.K every 5 meters and for that I need to use an expression in arcade, but I can't find the solution.
I am currently trying a conditional with the expression equal or default but I don't get what I am looking for.
Does anyone know what would be the expression to label those P.K every 5 meters?

Thanks to all of you who participate.

example code:

if (DefaultValue($feature.cngmetros, 0))
return Pkinicial
else (DefaultValue($feature.cngmetros, 5))
return PK5metros
else (DefaultValue($feature.cngmetros, ','))
return Pk5metros
else (DefaultValue($feature.cngmetros, '.'))
return Pk5metros

Greetings Javier

Could try something using the modulus operator.  Will return the remainder of the division, so it is evenly divided by 5, will return 0.

if ($feature.cngmetros % 5 == 0){
    return True //(or whatever value you require)
}

thanks to both of you for the help, related to this topic how could I label the pk's ending in decimal values.

As  RhettZufelt said, calculate the remainder of the division by 5 and make your code return values only when the remainder is 0. I tried it based on RhettZufelt code:

Result: labeling only multiples of 5:

I continue with this topic... I have already managed to mark the end of the P.K., but as always the arcade solutions leave much to be desired.....

with this expression I have succeeded:

just by looking at the image you would think that it has been achieved, but not because only 2 decimals can be shown in the P.k, so the round function would be very good, but .......

surprise:

disappears, the truth that I have no idea why to put a rounding disappears the value has been used the text function in case it does something but does nothing.

someone knows why this happens.

Your parren is in the wrong place.   Looks like you need to encapsulate the round function in parens, then compare != 0.

var inpval = $feature.cngmetros
if(inpval == 0 || inpval % 5 == 0 || Round(inpval % 1 != 0,2) != 0){
    return inpval
}

thank you for your reply.

I have tried your expression and it gives the same result, I do not understand why the round function does not round.

I found the solution and it was to declare the round in the return.

result:

Sorry, should have read the question better.  I just fixed the error in the round function so a label would show.
