Calculator is one of system applications in iOS, to which the owners of "apple" smartphones for the most part practically do not pay attention. For those who deal with constant calculations and calculations, the mobile calculator is rather an emergency replacement, but for other users, the application is a good help in certain situations.
In contact with
In addition to basic functions, "Calculator" on iPhone includes a number additional features which you might not know about.
The application features include a scientific calculator designed to perform complex mathematical calculations. Many of you are probably aware of its existence. iPhone owners. Rotating the device 90 degrees transforms the calculator's keyboard into a more functional interface with intuitively labeled buttons. Using the scientific calculator, math lovers will be able to extract roots, calculate logarithms and trigonometric functions.
Have you ever wondered where Apple put the back button, which allows you to correct a number in case of a mistaken entry? Many users use the key for this purpose. C (Reset) and, as a result, are forced to start the operation over. Apple has provided an easier solution to the problem - in order to delete the last entered digit, place your finger on a numerical value and swipe right or left. The direction of the swipe is not important - the application always deletes only the last entered digit. This gesture works in both vertical and horizontal modes.
With the release of iOS 10, switching between the Calculator and other applications has become much more convenient thanks to the support for 3D Touch. On devices that support 3D Touch "Command centre" includes function "Copy last result", eliminating the need for users to open the "Calculator" each time to access the results of the calculations.
Pressing the key again = » in the calculator will allow you to repeat the last action performed. For example, let's calculate what is equal to 80% of 1200 (1200 × 0.8 = 960). Each time the user presses "=", the application will re-perform the operation (that is, it will calculate 80% of 960, 80% of 768, etc.).
It so happened that the ipad does not have a calculator as a default application. This happened due to historical reasons, since Steve Jobs himself personally rejected the first calculator for the iPad. . Why is there no such desired application Where can I find the calculator app on my iPad? About this and not only we will talk in this article.
Before the presentation of the device in the operating system of the tablet, there was an application for doing mathematical calculations. It was simply copied from the iOS operating system, after which it was stretched to the entire display and shown to the founder Apple Steve Jobs. To which the founder replied that the design of the calculator itself did not suit him, after which he forced him to redesign the application or exclude it from the operating system.
This is not the first time a director has interfered with the work of the design department. The first Macintosh calculator was also rejected. As a result, Apple's chief designer wrote an application with which Steve could draw the design himself. Jobs did this work after which the design of the calculator was included in the main assembly of the operating system. The design of this application after that did not change for more than ten years.
There was little time before the official presentation, and there was no time left for reworking the application, so they decided to simply exclude it from the operating system. Source developers put the first iPad operating system on the Internet, and there were pieces of the first calculator. This application simply blocked, as a result of which it is almost impossible to find it in the system.
Tools for doing mathematical calculations in Apple tablets have always been lacking, but what can be done if the calculator is really needed? Official app the calculator will appear in the standard build of Apple starting with iOS versions 6. You can wait new version system and update or download an unofficial calculator.
To search and install new utilities, you will need an Internet connection. To download the program, you need to go to the official online application store from Apple, namely the AppStore. Write inside the search bar the program you are interested in by key features eg: pedometer, speedometer, stopwatch.
Run a search, then select the utility that is right for you. If it is paid, then pay for it, otherwise just download. After that, the program will stare and you can start working with it.
Since since the advent of the tablet, developers from different companies have worked tirelessly and during this time have written many worthy applications for calculations. You can choose the app that suits your taste and the features you want to see in it.
There are many free programs that can perform these functions. Most of them are free, but if you're looking for something more advanced, there are paid advanced versions as well. We will talk about some of them below.
smart enough and free program. With support for a currency converter, cosines of sines, has a timer on the bot, and also knows how to work with nine-digit numbers. The interface is intuitive and convenient, but the most interesting thing is that you can customize it for yourself. You can change the interface so that it would often desired functions were always in sight, this is its indisputable advantage.
A well-designed utility for calculations, developers should be given credit for such an implementation. Preferably for schoolchildren and students, as it is possible to view intermediate operations.
It knows how to solve problems, it contains basic formulas, and for an additional fee you can purchase an extended set of functions. It is possible to share the results directly from the application through social networks or by email.
This program is quite specific, but also interesting. It does not have the buttons we are used to with numbers or operations already applied. Instead of this convenient function, you will have to enter operations and numbers manually. This interestingness can be both confusing and can be an advantage, depending on your tasks. The program even has support for brackets, and can also fully understand them.
This utility is the simplest and most common calculator. If you do not need to calculate complex formulas every time, you are not interested in supporting many functions, but you need a simple rhyme with basic functions, then this program is your choice. Of the minuses, work only in vertical mode, that is, the application does not turn over, but is this really a problem for a tablet? Of the pluses, I can note the ability to change the background color of the program.
A calculator with the specific name calculator and dot. Nothing special simple utility for fast calculations. On the plus side, I can note reversibility, as well as work in two modes: vertical and horizontal; rather large buttons, as well as the presence of basic functions of addition, subtraction, multiplication, division.
Many iPhone users have recently begun to worry about the issue with the calculator. It either disappeared, or we just accidentally deleted it. Today I will tell you how you can restore the calculator on any iPhone.
To be more precise, on all devices that are equipped with an operating iOS system 10, because it is she who allows us to remove standard applications.
Almost everyone complained about this and Apple decided to fulfill the desire of its customers. So now, you don't have to create a folder for unnecessary applications.

And here I can say that the calculator can be launched from a locked iPhone. The control panel can also be called there. 
And by the way, do not forget about the horizontal mode, you will find a lot of useful features. Especially if you need to do more complex mathematical calculations.
Unlike the iPhone, the iPad does not standard application with a calculator. And this is a minus. But in the App Store you will find many applications that will solve this problem. As with any other category in the App Store, very few apps are worth your time. We've found the best iPad calculators for you.
