jlb071, that test expects false in every language, the next one expects true. In my previous post I was talking about jenThepilot test, not the OP. PHP tests aren't broken.

I agree the test data for PHP appears broken, in the given example above there is no element in array1 that when squared equals 36100 -- which is an element of array2.

It looks like that's optional, afaik.

Your points are not included in the array of your class's points. For calculating the average point you may add your point to the given array!

why?

jenThepilot: and why would that be false? That test is ok.

yes, I also think that is broken for PHP. It's expecting true in this case.
$a1 = [10000000,100000000];
$a2 = [100000000000000,10000000000000000];
$this->revTest(comp($a1, $a2), true);
