[ANSWERED] How to limit decimal output in Text Draw

[Gaspar]

Hi there,

I have a stream of floats that I want to display using the TEXT DRAW actor. However, I would display only up to the first or second decimal number.

So far I've tried to feed the data stream with the floats into a TEXT FORMATTER actor and from there into the TEXT DRAW actor. But I know neither how to define the format nor if that's even a valid approach.

I went through the manual, but I was unable to find a solution.

Any help is appreciated.

The Javascript code of @DusX s post did not work for me, but Javascript would sure be the cleanest way. But the approach with the text formatter also works fine. Just paste following into it:  P1:4.2 where 4 is how many number of digits are left of the decimal and 2 how many of digits right of the decimal.

@jfg @Michel

thank you both, since I had the formatter already implemented, I followed that one and it works great.

However, someday I'll have a look at the Javascript. It looks quite simple and might be a good starting point for learning to implement Javascripts.

Is there somewhere else, where I could lookm up the formatting commands? Somewhere other than the Izzy manual, from where I could not really understand it (blame it on me).

well I don't know were, but I usually use the infos inside Isadora (when hovering with the mouse). But I guess they are not different than the ones in the manual.

for me the problem with the javascript is that you don't get the 0 at the end of the decimal. You get 23 and not 23.00 or 23.1 and not 23.10.

The other problem I have is that you get with both (javascript and text formatter) a dot for decimal and not a comma as usual in Europe. Do you know a way to correct it.

thanks

Ok the code from @DusX does work, I just did not realise he put the Javascript into a user actor and therefore I did not change the input value to 2. I added the labelling of the inputs and output, this was added later to the Javascript actor. Well as far as I know JavaScript does not allow comma instead of a point. If you want that you have to convert the output to a string, but then you can't use it as number anymore. Even though Switzerland is in Europe we also use a point instead of a comma.

// iz_input 1 "float in"
// iz_input 2 "num of decimals"
// iz_output 1 "rnd val"
function main()
{
    function Nrnd(num, places){ 
        return +(Math.round(num + "e+" + places) + "e-" + places);
    }
    R = Nrnd(arguments[0],arguments[1]);
    return R;   
}

Hi there!

Happy to help. You use the JavaScript method .toLocaleString() for this. Basically you give it an valid language like "en-US" and provide the number and the decimals that you prefer.

See the example file.
