Results over about 3.4x10 38 were out-of-range. Revealed that the largest factorial it could manage was 34!, and that Standard of 69!, it told me the answer was infinite experimentation Identity it told me the answer was on the order ofġ0 -8 i, instead of zero. Supports complex numbers, but when I asked it to calculate Euler's When it comes to mathematics, the NumWorks didn't come off so well. Their TI-84 Plus calculators NumWorks does seem to be trying to be as free

It's really handy that the NumWorks is so intuitive, because the online manual I was able to get upĪnd running with graphs within two hours, something I still can'tĭo reliably on my TI-84 Plus after two years. Navigation controls at the top of the keypad. Other modes (suchĪs graphing and linear regression) are accessed via the high-level Key, which I took to be a print key for some hours. Sophisticated operations (integrals, sums and products, permutationsĪnd combinations, and the like) are accessed through the "toolbox" Less basic operations (trigonometric functions,Įxponentials, and complex numbers) are on the smaller keys above. Basic arithmetical operationsĪre all on the main keys. Which does make the workflow simpler than the TI's. Recalls the result of the previous calculation) are all on unshifted keys, π, the exponent function (x10 x), and Ans (which Wanted to avoid labels relating to advanced features crowding out theīasic function set). In poor light (Goyet says NumWorks may darken the ink used, but that it Print used for the alphabet functions on the keys is almost illegible TI's, offering color, a lot more pixels (320x240 versus 96圆4), andĭesign feel is much more video game than brick, though the gold-on-white
The NumWorks's screen is much better than the It's about the same width, an inch shorter, about half the thicknessĪnd slightly over half the mass of the TI and, at €80 or $100,Ĭompetitively priced. As an industrial product, the NumWorks compares well. My current calculator, the device against which I'm judging the NumWorks, The NumWorks device (currently the N100)Īnd Epsilon, the OS that the N100 runs, are the result. Manual to persuade his old calculator to do anything useful, and perceivingĬalculators in general to be user-hostile, unintuitive, and stuck inĪ rut, he decided to make a calculator that was easier to use and,Ĭrucially, easier to improve. Recalling how he'd had to spend hours poring over a He was looking to start his nextĬompany when he wandered into a supermarket and saw his oldĬollege calculator on the shelf - unimproved in over a decade and more Romain Goyet, the CEO, comesįrom a software engineering background. NumWorks was founded about two years ago. Is interesting to see to what extent it fulfills its promise. User-hostile position most calculator manufacturers have taken, and it Although it isįar from fully free at this point, it is a major step forward from the Recently, NumWorks, a new scientific graphingĬalculator with an open-design ethos was released. Still find a calculator a useful thing to have at hand. Many people now use their smartphones when they need to do sums, but In this case, the device is the humble scientific calculator. Its way into a class of devices that were not previously so blessed. So it's always of interest when freedom (or That open devices running free software (whether IoT devices or not) are It is an act of faith for some, myself included,
