This article is to share with you about the use of the CE key on a calculator. The editor thought it was very practical, so I shared it with you as a reference. Let's follow the editor and have a look.

The function of the CE key on the calculator is to clear the last entered error data. Calculators are generally composed of calculators, controllers, memories, keyboards, monitors, power supplies and some optional peripherals and electronic accessories, through manual or mechanical equipment.

Modern electronic calculator is a handheld electronic machine that can perform mathematical operations and has integrated circuit chips, but its structure is much simpler than that of computers. It can be said to be the first generation of electronic computers (computers) with weak functions, but it is more convenient and cheap. It can be widely used in commercial transactions, and it is one of the necessary office supplies. In addition to displaying the calculation results, there are often overflow indications, error indications, and so on. The calculator is powered by an AC converter or battery, which can be recharged with an AC converter or a solar converter. In order to save electricity, calculators use large-scale integrated circuits made by CMOS process.

Calculators are generally composed of calculators, controllers, memories, keyboards, monitors, power supplies and some optional peripherals and electronic accessories, through manual or mechanical equipment. The arithmetic unit and controller of low-end calculator realize simple serial operation by digital logic circuit, and its random memory has only one or two units for cumulative storage. High-end calculators implement a variety of complex operation programs by microprocessors and read-only memory, and there are more random storage units to store input programs and data.

Keyboard is the input component of calculator, generally using contact type or sensor type. In order to reduce the size of the calculator, one button often has a variety of functions. The display is the output component of the calculator, such as light-emitting diode display or liquid crystal display. Integrated circuits (see complementary metal-oxide-semiconductor integrated circuits) and internally equipped with timing-inoperable automatic power-off circuits. The peripherals available for calculators are micro-printers, cassette drives, magnetic card machines and so on.

In a way, the broad sense of "computer" includes "electronic calculator". There are also integrated circuits in electronic calculators, but calculators have simple functions, cheaper prices, and good portability and stability.

Thank you for reading! What is the use of the CE key on the calculator to share here, I hope the above content can be of some help to you, so that you can learn more knowledge. If you think the article is good, you can share it and let more people see it.
