Graphing calculator electrical power line transmission. Casio produced the first commercially available graphing calculator, the fx-7000G, in 1985. Casio's innovations include an icon menu for easy access to functions (1994, FX-7700GE and later), graphing in several colors (1995, CFX-9800G), textbook-like "Natural Display" input and output (2004, FX-82ES/300ES & FX-9860G), expandable memory (2005, FX-9860SD), backlit screen (2006, FX-9860G Slim), full-color, high resolution backlit screen (2010, FX-CG10/CG20 PRIZM). Sharp produced its first graphing calculator, the EL-5200, in 1986. Since then Sharp's innovations include models with a touchscreen (EL9600 series), Equation Editor (textbook-like input) (EL-9300 ( 1992 ) and later), and reversible keyboard to ease
Windows Calculator Windows Calculator Windows Calculator is a software calculator included in all versions of Windows. A simple arithmetic calculator was first included with Windows 1.0. In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression. In Windows 98 and later, it uses an arbitrary-precision arithmetic library, replacing the standard IEEE floating point library. It offers bignum precision for basic operations (addition, subtraction, multiplication, division) and 32 digits of precision for
