Though often stated as degrees, minutes, and seconds (or nowadays, as fractions of a degree), east or west, technically, declination west should be stated as negative degrees, minutes, and seconds (or fractions of a degree). So, if declination is greater than 42 degrees east, round down ;-). If declination is west, or 42 degrees or less east, round up. Hmmmm........ .
