bool result;

foreach (float number in numbers)
{
   result = Convert.ToBoolean(number);                                 
   Console.WriteLine("{0,-15}  -->  {1}", number, result);
}
// The example displays the following output: 
//       -3.402823E+38    -->  True 
//       -193.0012        -->  True
