Looks like an issue in FilipinoProvider

[wouterst79]

if (imod10 != 4 && imod10 != 6 || imod10 != 9) return PluralType.ONE;

this if statement always evaluates to true.. should it be

if (imod10 != 4 && imod10 != 6 && imod10 != 9) return PluralType.ONE;

BTW, here's my test code

    public interface IPluralProvider
    {
        float[] GetSampleValues();
        PluralType GetPluralType(float n);
    }


        public static void Test()
        {

            var interfacetype = typeof(IPluralProvider);
            foreach (var type in Assembly.GetExecutingAssembly().GetTypes())
            {
                if (interfacetype.IsAssignableFrom(type) && !type.IsInterface)
                {
                    var instance = (IPluralProvider)Activator.CreateInstance(type);

                    var values = instance.GetSampleValues();

                    var found = new HashSet<PluralType>();
                    foreach (var value in values)
                    {
                        var ptype = instance.GetPluralType(value);
                        if (!found.Add(ptype))
                        {
                            Console.WriteLine($"{type.Name} Duplicate type {ptype}: {value}");
                            foreach (var v2 in values)
                                if (instance.GetPluralType(v2) == ptype)
                                    Console.WriteLine($"\t({v2})");
                        }

                    }

                    for (float i = 0; i < 200; i++)
                    {

                        var ptype = instance.GetPluralType(i);
                        if (found.Add(ptype)) Console.WriteLine($"{type.Name} Missing sample type {ptype}: {i}");

                        ptype = instance.GetPluralType(i + .1f);
                        if (found.Add(ptype)) Console.WriteLine($"{type.Name} Missing sample type {ptype}: {i + .1f}");

                        ptype = instance.GetPluralType(i + .12f);
                        if (found.Add(ptype)) Console.WriteLine($"{type.Name} Missing sample type {ptype}: {i + .12f}");

                        ptype = instance.GetPluralType(i + .1243f);
                        if (found.Add(ptype)) Console.WriteLine($"{type.Name} Missing sample type {ptype}: {i + .1243f}");

                    }

                }
            }
        }
