What is a calculator without storage function?

Scientific calculator is a type of electronic calculator that can perform operations such as exponentiation, square root, exponent, logarithm, trigonometric function, statistics, etc. It is also called a function calculator.

In addition to displaying calculation results, modern electronic calculators often also have overflow indications, error indications, etc. The calculator uses an AC converter or battery as its power source, and the battery can be recharged with an AC converter or solar converter. A handheld electronic machine that can perform mathematical operations. It has an integrated circuit chip, but its structure is much simpler than that of a computer. It can be said to be the first generation of electronic computers (computers). Its functions are also weaker, but it is more convenient and cheap, and can be widely used. It is one of the necessary office supplies in business transactions.

Calculator structure

Calculator generally consists of arithmetic unit, controller, memory, keyboard, display, power supply and some optional Select peripheral equipment and electronic accessories, consisting of manual or machine equipment. The arithmetic unit and controller of low-end calculators use digital logic circuits to implement simple serial operations, and their random access memory has only one or two units for accumulation storage.

High-end calculators use microprocessors and read-only memories to implement various complex calculation programs, and have more random storage units to store input programs and data. The keyboard is the input component of the calculator, generally using contact type or sensor type. To reduce the size of the calculator, one button often has multiple functions. The display is the output component of the calculator, including a light-emitting diode display or a liquid crystal display.

In addition to displaying calculation results, there are often overflow indications, error indications, etc. The calculator uses an AC converter or battery as its power source, and the battery can be recharged with an AC converter or solar converter.

In order to save power, calculators use large-scale integrated circuits made by CMOS technology (see complementary metal-oxide-semiconductor integrated circuits), and are equipped with automatic power-off circuits inside when not operating. Optional peripherals for calculators include microprinters, cassette tape drives, and magnetic card machines.
