Editing Scientific calculator (section)

== Functions ==
When [[electronic calculators]] were originally marketed they normally had only four or five capabilities ([[addition]], [[subtraction]], [[multiplication]], [[Division (military)|division]] and [[square root]]). Modern scientific calculators generally have many more capabilities than the original four- or five-function calculator, and the capabilities differ between manufacturers and models. 

The capabilities of a modern scientific calculator include:

* [[Scientific notation]]
* [[floating-point arithmetic|Floating-point decimal arithmetic]]
* [[Logarithm]]ic functions, using both [[Common logarithm|base 10]] and [[Natural logarithm|base {{mvar|e}}]]
* [[Trigonometry|Trigonometric]] functions (some including [[Hyperbolic function|hyperbolic trigonometry]])
* [[Exponent]]ial functions and [[nth root|root]]s beyond the [[square root]]
* Quick access to [[Mathematical constant|constants]] such as [[pi|{{pi}}]] and [[E (mathematical constant)|{{mvar|e}}]]

In addition, high-end scientific calculators generally include some or all of the following:

* [[Cursor (user interface)|Cursor]] controls to edit [[Equation|equations]] and view previous calculations (some calculators such as the ''LCD-8310'', [[badge engineered]] under both ''[[Olympia Business Systems|Olympia]]'' and ''[[United Office]]'' keep the number of the previous result on-screen for convenience while the new calculation is being entered.<ref>{{cite web |title=Nostalgia & Fun With Calculators |url=https://ludditus.com/2019/02/10/nostalgia-fun-with-calculators/ |website=Homo Ludditus |date=10 February 2019}}</ref>)
* [[Hexadecimal]], [[Binary numeral system|binary]], and [[octal]] calculations, including basic [[Boolean logic|Boolean]] mathematics
* [[Complex numbers]]
* [[Fraction (mathematics)|Fractions]] calculations
* [[Statistics]] and [[probability]] calculations
* Programmability — see [[Programmable calculator]]
* [[Equation solving]] and [[computer algebra]] 
* [[Matrix (mathematics)|Matrix calculations]]
* [[Calculus]]
* [[Letter (alphabet)|Letters]] that can be used for spelling words or including [[Variable (mathematics)|variables]] into an equation
* [[Conversion of units]]
* [[Physical constants]]
* [[Vector (mathematics and physics)|Vector calculations]]
* [[Random number generation]]

While most scientific calculators have traditionally used a single-line display similar to traditional [[pocket calculators]], many of them have more digits (10 to 12), sometimes with extra digits for the floating-point exponent.  A few have multi-line displays, with some models from [[Hewlett-Packard]], [[Texas Instruments]] (both US manufacturers), [[Casio]], [[Sharp Corporation|Sharp]], and [[Canon (company)|Canon]] (all three Japanese makers) using [[dot matrix]] displays similar to those found on [[graphing calculator]]s.
