The first mechanical calculators were mechanical desktop devices, which were soon replaced by electromechanical desktop calculators, and then by electronic devices using first thermionic valves, then transistors, then hard-wired integrated circuit logic.

| | | | | List of calculators: Encyclopedia II - Calculator - Overview Modern calculators are electrically powered, most often by battery, and are made by numerous manufacturers, in countless shapes and sizes varying from cheap, give-away, credit-card sized models to more sturdy adding machine-like models with built-in printers. Only a very few companies develop and make modern professional engineering and finance calculators: The most well-known are Casio, Sharp, Hewlett-Packard (HP) and Texas Instruments (TI). Such calculators are good examples of embedded systems. They are also often complex enough to be programmed; calculator applications include algebraic equation so ...

| | | | | List of calculators: Encyclopedia II - Calculator - Use in education In most developed countries, students use calculators for schoolwork. There was some initial resistance to the idea out of fear that basic arithmetic skills would suffer. There remains disagreement about the importance of the ability to perform calculations by hand or "in the head", with some curricula restricting calculator use until a certain level of proficiency has been obtained, while others concentrate more on teac ...

| | | | | List of calculators: Encyclopedia II - Calculator - Calculators vs. computing A fundamental difference between a calculator and most computers is that calculators typically operate in Binary-coded decimal rather than binary as do computers. Also, the market for calculators is extremely price-sensitive; typically the user cares primarily about what is the least expensive model having a specific feature set, but does not care much about speed (since speed is primarily constrained by how fast the user can press the buttons). Thus designers of calculators strive to minimize the number of logic elements on the chip, no ...

| | | | | List of calculators: Encyclopedia II - Calculator - Other concerns on useage Errors are not restricted to school pupils. Any user could carelessly rely on the calculator's output without double-checking the magnitude of the result - i.e. where the decimal point is positioned. This problem was all but nonexistent in the era of slide rules and pencil-and-paper calculations, when the task of establishing the magnitudes of results had to be done by the sufficiently meticulous user.
Most everyday calculators are not completely accurate. There is a level of detail beyond which they truncate the number in memory, a s ...
