Arduino Code - Arduino Lesson 5 The Serial Monitor

Except the way that the Arduino software does this is that it creates a temporary variable the same size as drive_gb to store that calculation result before it sticks it into drive_mb. So basically we are still getting an overflow, except now its happening as we do the calculation.
