Plus42 is a programmable calculator based on Free42.
Like Free42, Plus42 has two calculator types, binary/decimal; it also has multiple skins from which to choose. Plus42 builds on Free42 by adding a larger display, including 8 rows and 22 columns (131x64 pixels) by default. You can resize the show at will; Algebraic Expressions modeled after those used on the HP-27S and HP-17B/19B; attached Units and unit conversions modeled after those used on the HP-48/49/50 series; Directories for more organized storage of programs and variables; TVM and amortization tables; and two-dimensional plotting of functions, with ability to zoom and pan, and find integrals and roots from points in the plot.
A detailed function description is available at the author's site to better understand the algebraic equations, modes, etc.
