>Have dealt with numerous tech support calls where people were peforming the incorrect computation on a calculator -- common mistake of entering HH:MM as HH.MM and adding and subtracting. Some pocket calculators -- usually scientific calculators, have a DMS/DEG key to convert between DDD.MMSS (degree, minutes, seconds) format to DDD.ddddd (fractions of degrees). Comes in handy when computing time.
