Filter DataTable.Select("column=4.4") misses for data type 'float'.
This is because of the way the Numeric class converts Single to Double

Reproducible: Always

Steps to Reproduce:
Test case

            DataTable table = new DataTable();
            DataColumn column = table.Columns.Add("column", typeof(float));
            DataRow row = table.Rows.Add((float)4.4);
            Debug.Assert((float)row[0] == (float)4.4);
            DataRow[] results = table.Select("column=4.4");
            Assert.AreEqual(1, results.Length);

Actual Results:  
The filter string does not match

Expected Results:  
The filter string matches

The problem is in the Numeric class which converts float to double.
