Sum dont work was created by brais24
Hi people, I think I found another bug, I attach the lss survey file with the survey

File Attachment:

File Name: limesurvey...2893.lss
File Size:25.12 KB


The thing is, if you fill this question (multiple numerical input with min sum value 50 and max sum value 100) with the data of the attached images

Limesurvey dont let you continue, say that the answer is incorrect even when its marked as correct.

Can someone help me with this, please?

Thank you.

Yes, seems to be a bug. Still happens in 3.25.1.

But you may validate the values instead using min.value and max.value
intval(10*sum(self.NAOK))/10 ge 50 AND intval(10*sum(self.NAOK))/10 le 100

On the other side: Talking about bugs in your outdated version (2.50/2.73, isn't it?) doesn't help.

Seems to be an issue … enter 50 on one and 0 on all other one : you can submit.

Maybe something with PHP version ?

Confirm on limequery too.

Can you report the issue ?
Currently : maybe you can set default values to 0 ?

No !!!

Your question are mandatory : mean need a value on all input …

Remove mandatory … if you want to have 50 at minum uncheck Value range allows missing

One question about the update, if I update from 2.72 to 3.25 the themes and other things of the surveys that I have already created can stop to work, right?

I check with 2.73.3 : seems OK

Maybe this fix needed : github.com/SondagesPro/LimeSurvey-Sondag...f16720c485eb3aa3e8e8

Please, yes.

Strangely

echo "sum(90,8,0.4,0.4,1.2) = ".array_sum([90,8,0.4,0.4,1.2]);
give

sum(90,8,0.4,0.4,1.2) = 100


Don't understand why it don't work …

Seems to be a php bug.

Small php-program:
Code:
<?php
echo "Sum of 90, 0.4, 0.4, 1.2 and 8<br><br>";
$i1=90;
$i2=0.4;
$i3=0.4;
$i4=1.2;
$i5=8;
$sum=$i1+$i2+$i3+$i4+$i5;
echo "Sum: ".$sum."<br>";
echo "Sum equal 100: ";if($sum==100) {echo "true";} else {echo "false";}
?>


Result:

Arg : totally right …

We use array_sum in Expression Manager / Script :
Code:
<?php
echo "array_sum([90,8,0.4,0.4,1.2]) = ".array_sum([90,8,0.4,0.4,1.2])."<hr>";
 
echo "array_sum([90,8,0.4,0.4,1.2]) == 100 : ";
echo (array_sum([90,8,0.4,0.4,1.2]) == 100) ? 'true' : 'false';

This is unrelated to PHP. It's how floating-point precision works. Can you use integers instead?
