Plus42 Description
Plus42 is an advanced scientific programmable calculator, based on Free42. Free42, in turn, is a complete re-implementation of the HP-42S scientific programmable RPN calculator, which was made from 1988 until 1995 by Hewlett-Packard. Free42 is a complete rewrite and contains no HP code whatsoever.

Plus42 builds on Free42 and adds: 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; a larger display, with 8 rows and 22 columns (131x64 pixels) by default, which the user may resize at will; time value of money and amortization schedules; and two-dimensional plotting of functions, with ability to zoom and pan, and find integrals and roots from points in the plot.
Plus42 1.0.21 Update
2023-08-17
Added string and list functions to the equation language. The new functions have been added to the FLAGS menu and CATALOG->FCN in the equation editor. List literals have the format {A:B:C}. List elements may be any type, including lists or matrices.

Equations: Fixed stack access within matrix literals.

Fixed LASTX option in the equation editor's stack menu (R↓ key).

Fixed Y^X with units where X is a negative reciprocal.

→LIST and LIST→ didn't print in TRACE mode. Fixed.

1.0.19 2023-05-05
Fixed the definition of the 'ton' unit (U.S. short ton). It was 10^10 times too large, due to a missing sign in the units definition table.

Equations like [1:2:3]=A, when entered without a name, weren't parsed correctly, because the part before the first colon would be incorrectly interpreted as a name. Fixed.

When an error occurs while evaluating an equation, and that equation exists in the EQN list, pressing R/S in the EQN list view will now start editing that equation, with the cursor on the part of the equation where the error occurred.
1.0.15 2022-12-14
Fixed a couple of bugs in Paste of scalars in BINM, OCTM, and HEXM modes.

Fixed pasting of U+22A2 and U+22A6 ('append' characters used by i41CX and Emu42) and U+00B7 ('bullet' character used by Emu42).
1.0.9 2022-06-19
SGN() didn't evaluate its parameter, and instead consumed the value from level 1. Fixed.

Note that this was a code generator bug; any expressions containing SGN() will have to be re-parsed in order to eliminate the effects of this bug.

SOLVE in PLOT, when used with a function with X:STK, would create an extraneous variable named "". Fixed.
1.0.4 2022-05-17
TVM: Fixed error checks in N.
1.0.3 2022-05-13
SOLVE now handles functions that are always positive or always negative a bit better, reporting Extremum when the iteration appears to be bouncing around without improving, instead of continuing indefinitely.

PLOT now detects 'Not a Number' in XMIN/XMAX/YMIN/YMAX and reports Invalid Data, instead of freezing.
1.0.2 2022-05-09
Added code to prevent freeze in PLOT under certain circumstances.
1.0.1 2022-05-06
DIM "X", when X existed but was not a matrix, would cause a crash. Fixed.

Equations: NOT was broken, not recognized as Boolean operator. Fixed.

Equations: Added TYPE? and UNIT? functions.
