Plus42 1.3.10c

Plus42 is an advanced programmable scientific calculator based on the Free42 project, a complete reimplementation of the HP-42S, a programmable RPN scientific calculator manufactured by Hewlett-Packard from 1988 to 1995. Plus42 expands the features of Free42, offering a larger screen of 8 rows and 22 columns (131x64 pixels) that can be resized, as well as supporting algebraic expressions and measurement units with conversions inspired by the HP-48/49/50 calculators. Other features include directories for organizing programs and variables, financial calculations, amortization tables, and two-dimensional graphs with zoom, pan, and analysis functions for integrals and roots.
