Python, probably other languages too: missing tests with even floats, there are a lot of ncorrect solutions.

No random tests in

• C#
• Java
• Javascript

use long int instead of int because high precision floats cause problem

Most solutions would fail a high precision float test.

That one also shows signs of much more effort.

• same description of a very slight variant on the same problem, same solution code with minor modifications

A requirement of this kata is that floats should always return false.

The "float numbers" test needs an negative assertion which will not round up to an odd number, something like:

assert even?(1.8) == false

Otherwise, you get solutions like this passing: http://www.codewars.com/kata/reviews/57729f4b9b79815fca000192/groups/590636e1798d70810600107f

Your solution should return [] if all values in the array are not numbers.

Why we should return '[]' (a string) instead of [] (an array)? This makes zero sense.

Needs random tests.
