Maxima is a computer algebra system based on a 1982 version of Macsyma. It is written in Common Lisp and runs on all POSIX platforms such as macOS, Unix, BSD, and Linux as well as under Microsoft Windows and Android. It is free software released under the terms of the GNU General Public License.
Maxima is based on a 1982 version of Macsyma, which was developed at MIT with funding from the United States Department of Energy and other government agencies. A version of Macsyma was maintained by Bill Schelter from 1982 until his death in 2001. In 1998, Schelter obtained permission from the Department of Energy to release his version under the GPL. That version, now called Maxima, is maintained by an independent group of users and developers. Maxima does not include any of the many modifications and enhancements made to the commercial version of Macsyma during 1982–1999. Though the core functionality remains similar, code depending on these enhancements may not work on Maxima, and bugs which were fixed in Macsyma may still be present in Maxima, and vice versa.
Maxima includes a complete programming language with ALGOL-like syntax but Lisp-like semantics. It is written in Common Lisp, and can be accessed programmatically and extended, as the underlying Lisp can be called from Maxima. It uses Gnuplot for drawing.
Maxima is a full-featured CAS (computer algebra system) that specializes in symbolic operations but it also offers numerical capabilities such as arbitrary-precision arithmetic: integers and rational numbers which can grow to sizes limited only by machine memory, and floating point numbers whose precision can be set arbitrarily large ("bfloats").
