Qalculate! is an arbitrary precision cross-platform software calculator. [9] It supports complex mathematical operations and concepts such as derivation, integration, data plotting, and unit conversion. It is a free and open-source software released under GPL v2.
The "Small" prefix in the name SmallBASIC reflects the project's original intention of being used with the Palm, a small hand-held device.SmallBASIC was designed for portability, and is written in C with separate modules containing any code that is unique to a particular platform.
OWBasic was an implementation of the BASIC programming language. OWbasic has most of the BASIC commands such as proc, gosub , conditional if/then statements and some others for graphing. OWBasic also allows a user to develop applications for string text, taking the CasioPV beyond the normal limits imposed by a standard programmable calculator.
Made in Japan, this was also the first calculator to use an LED display, the first hand-held calculator to use a single integrated circuit (then proclaimed as a "calculator on a chip"), the Mostek MK6010, and the first electronic calculator to run off replaceable batteries. Using four AA-size cells the LE-120A measures 4.9 by 2.8 by 0.9 inches ...
In addition to providing users with scientific math functions in a small portable package, the devices also understood a form of the BASIC programming language. They included a QWERTY keyboard , of either rubber capacitive or membrane type , to use for entering the names of scientific functions and programming commands, in addition to a ...
As a calculator, rather than a computer, they usually have a small set of relatively simple operations, perform short processes that are not compute intensive and do not accept large amounts of input data or produce many results, though many software calculators can emulate handheld scientific calculator and graphing calculator features such as ...
This free software had an earlier incarnation, Macsyma. Developed by Massachusetts Institute of Technology in the 1960s, it was maintained by William Schelter from 1982 to 2001. In 1998, Schelter obtained permission to release Maxima as open-source software under the GNU General Public license and the source code was released later that year ...
A simple arithmetic calculator was first included with Windows 1.0. [5]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.
