Most people will probably find this calculator a bit overkill. While this isn’t a deal breaker, it is a point against the professionalism of the program. Finally, the program does have some typographical errors. My personal favorite is the Snowy Plain because it looks stylish and professional. Thankfully, it doesn’t cost anything at all to replace the theme. Quite frankly, all of the other themes the program provides look a lot better than the default one. Keeping it in portrait mode simulates the look of a real-life calculator a little better, but the landscape mode is easier to look at and use. That said, you can change the theme as well as the orientation of the program. You’ll actually find that some of the buttons cut off at the bottom. It has a black design that doesn’t fit into the small interface. When you first launch the program after installing it, its appearance is admittedly not very good. Anyone who has ever looked at one of these fancy scientific calculators and became majorly confused can bid their confusion goodbye since all you have to do is hover over buttons to understand them. A tooltip with explanations of all the major function buttons in the calculator appears whenever you hover over said buttons. In addition, the calculator has an incredibly useful feature for anyone not inclined to mathematics or need a refresher. This will make your computations so much easier and your workflow so much more efficient instead of having to click the buttons manually every time. One great thing about this calculator is the fact that you can assign the basic functions with hotkeys. There are also buttons to compute for pi, add exponents, and more. Probably the most important is are the actual mathematical functions such as s ine, cosine, and tangent functions. The HiPer Calc has a lot of features and functions that many ordinary calculators do not possess. It is a digital scientific calculator that has a lot of functions that most mathematicians will appreciate. The HiPer Calc by HiPer Development Studio is here to provide a solution to that need. For people like these, they’re going to need a calculator that has a lot more functions. This is certainly not the case for people whose professions involve a lot of mathematics and calculations. So users can know how much memory they can use safely and make sure user's progames and data can be safely preserved on disk.A lightweight calculator with scientific functionsįor most people, a standard calculator that can add, multiply, divide, and subtract would be more than enough to fulfill their needs. When the app starts it can ask that much to opeartion system for use. Let users to choose how many memory they want. Does free42 still have these limitations? Maybe it can jump more than 1000 steps and remember more locations for program to return.Įmus48 uses a file to simulate memory which a calculator has. Such as GOT function can't jump to subroutines more than 1000 steps and for RTN fucntion Hp-42s can remember up to 8 pending return locations. Hp-42s has some limitation for it's programes. Since free42 uses C++ runtime system to manage memory. Probably before you hit the absolute limit, the performance of your computer/phone/tablet will start to suffer. At some point you'll hit a limit, but it's difficult to predict where that limit would be. Unfortunately, wanting to know this for Free42 is sort of like wanting to know how many pages you can type into Microsoft Word, or how many tabs you can open in your web browser. The HP-42S fimrware managed it very closely, and always knew exactly how much unused RAM was present. Free42 on a computer/phone/tablet works nothing at all like the HP-42S, which had exactly 8192 bytes of RAM (unless you cracked it open and put in more). Quote:How many memory of free42's can be used safely? In the latter case, usually more than is immediately needed is given by the operating system to the runtime system, hence an allocation can actually cause free memory (within the application) to go up. With Free42, the memory is managed by the C++ runtime system, so when memory has to be allocated by the calculator, it may be allocated from memory that the operating system (Windows MacOS, Linux, Android, etc.) has already given to the runtime system, or the runtime system may ask the operating system for more.
