Examples

The following code example compares a BitVector32 with another BitVector32 and with an Int32.

   if ( myBV.Data == myInt32 )
      Console::WriteLine( "   Using the \"==\" operator, myBV.Data( {0}) equals myInt32( {1}).", myBV.Data, myInt32 );
   else
      Console::WriteLine( "   Using the \"==\" operator, myBV.Data( {0}) does not equal myInt32( {1}).", myBV.Data, myInt32 );
}

Remarks

The object o is considered equal to the BitVector32 if the type of o is compatible with the BitVector32 type and if the value of o is equal to the value of Data.

This method is an O(1) operation.
