Design Scientific calculator displays of fractions and decimal equivalents InputĮlectronic calculators contain a keyboard with buttons for digits and arithmetical operations some even contain "00" and "000" buttons to make larger or smaller numbers easier to enter. By 2007, this had diminished to less than 0.05%. In 1986, calculators still represented an estimated 41% of the world's general-purpose hardware capacity to compute information. With the very wide availability of smartphones and the like, dedicated hardware calculators, while still widely used, are less common than they once were. As of 2016, basic calculators cost little, but scientific and graphing models tend to cost more. Graphing calculators can be used to graph functions defined on the real line, or higher-dimensional Euclidean space. Some calculators even have the ability to do computer algebra. For example, there are scientific calculators which include trigonometric and statistical calculations. In addition to general purpose calculators, there are those designed for specific markets. Calculator functions are included in most smartphones, tablets and personal digital assistant (PDA) type devices. By the end of that decade, prices had dropped to the point where a basic calculator was affordable to most and they became common in schools.Ĭomputer operating systems as far back as early Unix have included interactive calculator programs such as dc and hoc, and interactive BASIC could be used to do calculations on most 1970s and 1980s home computers. They became popular in the mid-1970s as the incorporation of integrated circuits reduced their size and cost. Modern electronic calculators vary from cheap, give-away, credit-card-sized models to sturdy desktop models with built-in printers. Pocket-sized devices became available in the 1970s, especially after the Intel 4004, the first microprocessor, was developed by Intel for the Japanese calculator company Busicom. The first solid-state electronic calculator was created in the early 1960s. For other uses, see Calculator (disambiguation).Īn electronic pocket calculator with a seven-segment liquid-crystal display (LCD) that can perform arithmetic operations A modern scientific calculator with an LCDĪn electronic calculator is typically a portable electronic device used to perform calculations, ranging from basic arithmetic to complex mathematics. For mechanical precursors to the modern calculator, see mechanical calculator. This article is about the electronic device.
