Movilizer: How to get integer result after calculation with getAnswerValue() return values?

I'm working with a Text Item screen (type="5") that includes Answers for integer numeric input (attributeType="2"). Now, when I perform a calculation with the user input values, the return value is always a float numeric.

Shortened example:

<question key="#1" type="5" title="My Screen">
    <answer key="#1_1" attributeType="2" nextQuestionKey="#2">
        <text>Num1</text>
    </answer>
    <answer key="#1_2" attributeType="2" nextQuestionKey="#2">
        <text>Num2</text>
    </answer>
    <text>Enter 2 numeric values</text>
    <onLeaveOkPersistAssignment>
        val1 = getAnswerValue($answer:'#1_1'); <!-- for example '1' --> 
        val2 = getAnswerValue($answer:'#1_2'); <!-- for example '2' -->

        $local:result = val1 + val2;
    </onLeaveOkPersistAssignment>
</question>
<question key="#2" type="0" title="My Screen">
    <answer key="#2_1" nextQuestionKey="END">
        <text>%PLC%</text>
    </answer>
    <text>The result is:</text>
    <onEnterAssignment>
        setPlaceholder('%PLC%', $local:result); <!-- the screen should display '3' not '3.0' -->
    </onEnterAssignment>
</question>

Is there a possibility to return an integer or at least convert the value into an integer?

The easiest approach I can think of is the following:

$local:result = (val1 + val2) \ 1;

Simple integer division by 1 gets rid of the decimal rest and works on numerics and not only strings as parseInt does.

what you can use is the method to convert the given format into int

myInt = parseInt(answerVal, 10)

in your case it will look like that:

<onLeaveOkPersistAssignment>
    val1 = getAnswerValue($answer:'#1_1'); <!-- for example '1' --> 
    val2 = getAnswerValue($answer:'#1_2'); <!-- for example '2' -->

    val1 = parseInt(val1, 10);
    val2 = parseInt(val2, 10);
    $local:result = val1 + val2;
</onLeaveOkPersistAssignment>
