Editing Calculator (section)

===Display output===
Calculators usually have [[liquid-crystal display]]s (LCD) as output in place of historical [[light-emitting diode]] (LED) displays and [[vacuum fluorescent display]]s (VFD); details are provided in the section ''[[#Technical improvements|Technical improvements]]''.

Large-sized [[Number|figures]] are often used to improve readability; while using [[decimal separator]] (usually a point rather than a [[comma]]) instead of or in addition to [[vulgar fraction]]s. Various symbols for [[Command (computing)|function commands]] may also be shown on the display. [[Fractions]] such as {{math|{{frac|1|3}}}} are displayed as decimal [[approximation]]s, for example rounded to {{math|0.33333333}}. Also, some fractions (such as {{math|{{frac|1|7}}}}, which is {{math|0.14285714285714}}; to 14 [[significant figures]]) can be difficult to recognize in [[decimal]] form; as a result, many [[Scientific calculator|scientific]] calculators are able to work in vulgar fractions or [[mixed number]]s.
