title: pass a list of floating point numbers to a DUNIT testcase
body: <p>I need  to pass a set of floating point values to a Delphi DUNITX testcase .
  The  solution with adding the separator char does not work for me.</p>
  <p>Test_Int has the complete string and I can extract the  stored integer values,
  the  separator char as optional  param does not have  any function acc. to  my  trials.</p>
  <p>This  is  opposite to solution from <a href="https://stackoverflow.com/questions/44538544/unit-testing-how-can-i-pass-string-with-comma-to-a-testcase-in-dunitx">send 1 floating  point number</a>
  and  therefore  I fail with  transferring the  string with multiple real values.</p>
  <pre><code>    [Test]
      [TestCase('Test_Int', '1,2,3,4,5,6', ';')]
      procedure Test_Integer(const AValue1: String);
  
  
      [Test]
      [TestCase('Test_Floata', '1.5;2.4;3.4;5.6;7.0;8.0', ';')]
      [TestCase('Test_Floatb', '1,5;2,4;3,4;5,6;7,0;8,0', ';')]
      procedure Test_Floating(const AValue1: String);
  
  
  
  procedure Test.Test_Floating(const AValue1: String);
  begin
         xxxx:=AVlaue   // only get first  number :-( 
  end;
  </code></pre>
