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

array<float>^ numbers = gcnew array<float> { Single::MinValue, (float) -193.0012, (float) 20e-15f, 0, 
                                             (float) 10551e-10, (float) 100.3398, Single::MaxValue };
bool result;

for each (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
//       100.3398         -->  True
//       3.402823E+38     -->  True
