I have run into the same problem, and have found a quite simple solution: use a custom validator, which does not return "valid" when the Text ends in "." or "0":

double val = 0;
string tmp = value.ToString();

if (tmp.EndsWith(",") || tmp.EndsWith("0") || tmp.EndsWith("."))
{
    return new ValidationResult(false, "Enter another digit, or delete the last one.");
}
else
{
    return ValidationResult.ValidResult;
}
