The following example converts an array of Single values to Boolean values.

                    10551e-10f, 100.3398f, Single.MaxValue };
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 
//       2E-14            -->  True 
//       0                -->  False 
//       1.0551E-06       -->  True
