Technically your code is bugged. It works because of an implementation detail of both the test cases and the interpreter, but pairs doesn't iterate arrays in order. In this case, ipairs should be used instead.

You could also use the index when inserting into the result table, instead of re-calculating its length every time, which is an "expensive" operation. This would also fix the problem I mentioned above (Though I'd still recommend using ipairs, for several reasons)

Edited descriptions

agreed. 5.23 should be True since the int representation as well as the full float are odd.

Need or more information in the description -Only return l1- or more Tests.

This kata ever return:
SyntaxError: Unexpected token )
at Object.Function
at NoNumbersObject

I think this kata need more tests.

In floats inputs the solutions are wrong...
