Template:Cleanup-date Image:Hp42s face.jpeg The HP-42S is a programmable hand held calculator with advanced functions suitable for those involved in mathematics, linear algebra, statistical analysis, computer science and other applications.
The HP-42S was released as a replacement for the aging HP-41 series. It was designed to be compatible with all programs written for the HP-41. Additionally, it features a two-line dot matrix display, which made stack manipulation easier to follow. The HP 42S, however, received criticism for its lack of expandability, and lack of any real I/O ability, both key features of the HP41 series. The 42S, however, has a much smaller form factor than the 41, and features many more built-in functions, such as a matrix editor, complex number support, an equation solver, user-defined menus, and basic graphing capabilities. In the HP calculator community, the 42S is infamous for its inflated prices in online auctions.
