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.
What’s New
Version 1.1.12
Fixed handling of ºC and ºF return values in numeric solver.
Ratings and Reviews
why does this calculator can only store 4 numbers?
Hope can store more numbers
Developer Response ,
You can store as many numbers as you like using STO. Or, if you want more than 4 stack levels, you can use the dynamic stack, by switching to NSTK mode: MODES ▲ NSTK. (You can return to the 4-level stack mode with MODES ▲ 4STK.)
Can’t import programs
No files or directory can be seen with the Files App as Free42. How can I copy programs from Free42 to Plus42 and import them? And the author’s website can’t be accessed.

Sorry for the slow reply, I never got the notification about your question. Note that reviews aren't a good place for asking questions; it is much more convenient to contact the author using email. Thanks!
非常好的模拟器,如果能支持iOS 9就更好了
App功能非常强大,如果能支持低版本的iOS就更好了,比如iOS 9.3 ,这样就可以在一些老的iPad,或者iPhone上安装它。
希望开发者能认真考虑一下这个建议。
Developer Response ,
Unfortunately, Apple's current software development tools only support iOS 12 or later.
