Hopefully this will give you some hints into the challenges that you will face.Īnother thing to consider is most calculators carry more digits than they display. Clearly cost has multiple independent variables that would act as confouding variables for your problem. But what about going to Wal-Mart and buying a discount calculator for $10.00 that has 8 decimal places, and then going to Sharper Image and buying one for $20.00 that has only 4 decimal places (but has a neat bottle opener, laser pointer, corkscrew, and emergency beacon.) This would be comparing apples and oranges. PI), you can find an inherent accuracy difference which is solely based on the number of digits reported. Now, if you use an infinitely repeating answer (e.g. It is also 100% accurate.Ī really big calculator with 16 decimal places will return a value of 4.0000000000000000. It is 100% accurate.Ī slightly better calculator with 4 decimal places will return a value of 4.0000. The correct answer is 4.Ī cheap calculator with one decimal place will return the value of 4.0. The problem is finding a method to test it. I think a calculator that can display 15 digits (including guard digits) after the decimal point in a calculation is more accurate than a calculator which can only display 10 digits after the decimal point. I am thinking about the number of digits that can be shown in a scientific calculation of a certain calculator and from there determining the degree of accuracy of that specific calculator. I know that calculators are accurate most of the time, but I am testing the degree of accuracy of calculators, like "low accuracy", "normal accuracy", "good accuracy", "very good accuracy", "extremely good accuracy", etc. By accuracy, I mean "Accuracy is the degree of conformity of a measured or calculated quantity to its actual (true) value". If you can think of a better hypothesis, tell me and I will consider changing it. Well, I know that price (money) is not a very objective factor in science, but I cannot think of anything else. State saving.Does the price of a calculator affects its accuracy?.Get any numbers from your computation history to carry out new calculations Numbers break up into groups of digits in accordance with your regional standards Conduct massive calculations instantly with the ability to duplicate results you've already computed Carry out calculations in radians or degrees All the calculations you need can be stored for an unlimited time.
