Rounding on problem sets and exams Rounding is an issue in this class. As a rule of thumb, if the question doesn’t specify and you need to round your final answer, you should round it to four decimal places. Always use the common method of rounding. http://en.wikipedia.org/wiki/Rounding: Common method This method is commonly used in mathematical applications, for example in accounting. It is the one generally taught in elementary mathematics classes. This method is also known as Symmetric Arithmetic Rounding or Round-Half-Up (Symmetric Implementation) Decide which is the last digit to keep. Increase it by 1 if the next digit is 5 or more (this is called rounding up) Leave it the same if the next digit is 4 or less (this is called rounding down) Examples : 3.044 rounded to hundredths is 3.04 (because the next digit, 4, is less than 5). 3.045 rounded to hundredths is 3.05 (because the next digit, 5, is 5 or more). 3.0447 rounded to hundredths is 3.04 (because the next digit, 4, is less than 5).
