Identify iOS Firmware File to Download based on your iPhone Model.If you’re not sure which firmware file to download for your iPhone, then check the post which will help you identify which firmware file to download based on your iPhone’s model. It certainly is one of the best, if not the best-advanced math desktop calculator app out there.Below are the direct links for the iOS firmware updates that have been released for the iPhone by Apple so far. However, in the case of Qalculate!, the usage of this expression seems befitting. We don't usually like to use the word 'ultimate,' because, well, even if an app is good or the best today, tomorrow it might be overthrown by a newer product. In addition, you can also edit/create functions, variables and units, effortlessly edit matrices and vectors, and perform fast conversions between number bases, floating point conversion, calendar conversions, and percentage calculations (and it even has a period table). The GUI is built using GTK (or Qt) so it looks very nice, it has calculation history, practical menus for fast access to all the advanced features, customizable meta modes, dialog management options, and configurable keyboard shortcuts. What else?īesides having an outstanding library, Qalculate! also excels when it comes to user experience. You can find a complete list of all the supported functions, units, variables, and some nice examples on the app's official website. The list goes on with the ability to calculate uncertainty propagation, interval arithmetic, and plotting scenarios. However, what makes Qalculate! so special is its insanely massive library which includes a plethora of customizable functions, unit calculations, conversions, physical constants, symbolic calculations (including integrals and equations), and arbitrary precision. It looks like pretty much any complex calculator out there, and it's actually quite user-friendly. The short answer is - surprisingly capable.

It's also free, open-source, and cross-platform (it works on all major OSes out there such as Windows, macOS, and most Linux distributions. Qalculate! (GTK) is an incredible, little multi-purpose calculator that can handle pretty much everything thrown at it including complex math equations and functions, as well as currency conversions, and percent calculations.

However, for university students, researchers, and scientists, having an advanced calculator capable of dealing with complex mathematical operations is a must. For most people, the calculators on our smartphones are quite enough.
