Calculator is a basic calculator application made by Apple Inc. and bundled with its macOS, iOS, and watchOS operating systems. It has three modes: basic, scientific, and programmer. The basic mode includes a number pad, buttons for adding, subtracting, multiplying, and dividing, as well as memory keys. Scientific mode supports exponents and trigonometric functions. The macOS version of Calculator also has a programmer mode that gives the user access to more options related to computer programming . [1]
The Calculator program has a long associated history with the beginning of the Macintosh platform, where a simple four-function calculator program was a standard desk accessory from the earliest system versions. Though no higher math capability was included, third-party developers provided upgrades, and Apple released the Graphing Calculator application with the first PowerPC release (7.1.2) of the Mac OS, and it was a standard component through Mac OS 9. Apple also ships a different application with macOS called Grapher for this purpose. [2]
A calculator function has been included with iOS since its launch on iPhone [3] and iPod Touch. [4] However, iPads have never had a first party calculator application. A native calculator function was added to the Apple Watch with watchOS 6, which included a dedicated button for calculating tips. [5]
Calculator has Reverse Polish notation support, and can also speak the buttons pressed and result returned.
The calculator also includes some basic conversion functions to convert between units in the following categories:
Since the release of Mac OS X Leopard, simple arithmetic functions can be calculated from the Spotlight feature. [7] They include the standard addition, subtraction, multiplication, and division operations, with exponentiation and the use of the percent sign to denote percentage.
A Dashboard Calculator widget was included in all versions of macOS from Mac OS X Tiger onwards until Mojave, after which Dashboard was discontinued. It only has the basic mode of its desktop counterpart. With the release of OS X Yosemite, unit conversion functions were added to the Spotlight calculator, [8] as well as a simple calculator widget available in the Notification Center. [9]
The Calculator appeared first as a desk accessory in first version of Macintosh System for the 1984 Macintosh 128K. Its original incarnation was developed by Chris Espinosa and its appearance was designed, in part, by Steve Jobs when Espinosa, flustered by Jobs's dissatisfaction with all of his prototype designs, conceived an application called The Steve Jobs Roll Your Own Calculator Construction Set that allowed Jobs to tailor the look of the calculator to his liking. Its design was maintained with the same basic math operations until the final release of classic Mac OS in 2001. [10]
The Calculator app is not available on Apple's iPad tablet. In 2020, when asked about it by American tech YouTuber Marques Brownlee, Apple software chief Craig Federighi responded that Apple had not found a design that would "do justice" to the iPad's screen size. [11] In 2022, the Wall Street Journal's Joanna Stern asked Apple marketing chief Greg Joswiak, who responded: "There are a ton of them. Go to the App Store." [12] [13] A jailbreak tweak named "Belfry" was able to unofficially install the app, along with every other iPhone-only application on an iPad in early 2012. [14]
The history of macOS, Apple's current Mac operating system formerly named Mac OS X until 2011 and then OS X until 2016, began with the company's project to replace its "classic" Mac OS. That system, up to and including its final release Mac OS 9, was a direct descendant of the operating system Apple had used in its Mac computers since their introduction in 1984. However, the current macOS is a UNIX operating system built on technology that had been developed at NeXT from the 1980s until Apple purchased the company in early 1997.
iPhoto is a discontinued digital photograph manipulation software application developed by Apple Inc. It was included with every Mac computer from 2002 to 2015, when it was replaced with Apple's Photos application. Originally sold as part of the iLife suite of digital media management applications, iPhoto is able to import, organize, edit, print and share digital photos.
Contacts is a computerized address book included with the Apple operating systems iOS, iPadOS, watchOS and macOS, previously Mac OS X and OS X. It includes various cloud synchronization capabilities and integrates with other Apple applications and features, including iMessage, FaceTime and the iCloud service.
Newton OS is a discontinued operating system for the Apple Newton PDAs produced by Apple Computer, Inc. between 1993 and 1997. It was written entirely in C++ and trimmed to be low power consuming and use the available memory efficiently. Many applications were pre-installed in the ROM of the Newton to save on RAM and flash memory storage for user applications.
Stevenote is a colloquial term for keynote speeches given by Steve Jobs, former CEO of Apple, at events such as the Apple Worldwide Developers Conference, Macworld Expo, and Apple Expo. Because most Apple product releases were first shown to the public at these keynotes, "Stevenotes" caused substantial swings in Apple's stock price.
Dashboard is a discontinued feature of Apple Inc.'s macOS operating systems, used as a secondary desktop for hosting mini-applications known as widgets. These are intended to be simple applications that do not take time to launch. Dashboard applications supplied with macOS included a stock ticker, weather report, calculator, and notepad; while users could create or download their own.
iOS is a mobile operating system developed by Apple Inc. exclusively for its smartphones. It was unveiled in January 2007 for the first-generation iPhone, launched in June 2007.
SpringBoard is the standard application that manages the iPhone's home screen. Other tasks include starting WindowServer, launching and bootstrapping applications and setting some of the device's settings on startup.
iPadOS is a mobile operating system developed by Apple Inc. for its iPad line of tablet computers. It was given a name distinct from iOS, the operating system used by Apple's iPhones to reflect the diverging features of the two product lines, such as multitasking. It was introduced as iPadOS 13 in 2019, reflecting its status as the successor to iOS 12 for the iPad, at the company's 2019 Worldwide Developers Conference.
