About RPN-34 CE
RPN-34 CE is the first photo-realistic simulation of Hewlett-Packard's popular mid-range scientific calculator HP-34C for the iPhone. Produced from 1979 through 1983, it was the "Basil" member of the third-generation HP calculators known as the "Spice" series.
It was the first pocket-calculator ever capable of doing integration and root finding.
While the simulator works like the original calculator, a number of carefully designed extensions, along with the tremendously improved speed, make it joy to use even today.
RPN-34 CE comes with the programs of HP's "Applications", "Mathematics", "Surveying", "Student Engineering", and "Statistics" application books built-in! Handbooks may be downloaded from CuVee Software's website.
Features:
• Photo-realistic look-and-feel
• Programmable (999 steps), subroutines, 12 labels, 10 flags
• 100 registers, "continuous", with full store/recall arithmetic
• "Live" register view
• Program listing view with intelligent navigation
• Program library, easily backed-up via iTunes
• Store and retrieve any number of programs
• Sharing: e-mail, AirDrop, Dropbox, copy, paste, print
• 59 programs pre-installed (53 original HP)
Calculator functions:
• Integration, root solving
• Statistics (mean, standard deviation, linear regression, normal distribution)
• Factorial of any number (normal and logarithmic)
• Trigonometric and hyperbolic functions (degrees, radians, grads)
• Polar/rectangular conversions
• Inverse, square root, logarithm, exponential, pi
• Storage arithmetic (both store and recall)
• Statistics (average, standard deviation, y-estimate, linear regression)
• Unit and hours conversions
• 31 additional functions not found on the HP-34C, like time and sound

What's New in the Latest Version 2.6
Last updated on Jan 15, 2024
Old Versions
• After computing an integral, the "uncertainty" stack register Y contains the current "Integration Accuracy" setting (0 = Best, 1 = High, 2 = Norm).
• The "Integration Accuracy" setting is now stored along with the program.
• Added "-" following the step number in PRGM mode, as on a real HP-34.
• The display now may show dashes on lengthy calculations.
• Verified and cleaned up descriptions of many sample programs.
• New sample programs added: "Double Integrals" and "Memory Game and Trainer".
• Bug Fixes:
- The previous version 2.5 didn't drop the stack on y^x.
- Suppressed illegal key sequences, like "LBL CHS" or "LBL +" etc.
– "SOLVE lbl" is now correctly listed as "14 73 lbl", not "14 .lbl" (where lbl = 0..9, 11, 12).
- In PRGM mode, two consecutive RTN steps could show up at the end of a program.

• Haptics
Set the haptic feedback level in the calculator's settings.
„Sounds & Haptics“ / „System Haptics“ must be on in the iPhone's settings.
• Improved Indirect Branching
Labels .0 and .1 may now be targets of indirect branching
via the I-register if extended registers 0..99 are enabled.
• Program list view can be dragged down to dismiss it.

• Print (or mail as PDF) the program or its description
• Improved accuracy in extreme cases of y^x with positive, integer x.
For example, 1.0000001^(2^27) = 674530.4707, not 674530.4760
• Stack shows localized formatted value while number is being entered
• Call up "What's New" anytime from Info screen
• Compatibility with iPhone 12
Bug Fixes:
• Fixed display issues when using the iPhone in "Zoomed" mode
• The RND function didn't work correctly in regions using a comma as decimal point
• Double- or triple-tapping the empty program listing could cause a crash.

• Improved LN(x!) function:
- Higher accuracy
- Now returns y and z such that x! = y * 10^z (where z is an integer)
• If SOLVER is called from a program, and a root is not found, the program doesn't stop anymore. Instead, the next step is skipped. This allows iterative searching for roots under program control.
• Improved stack display (swipe display right to show):
- Doesn't cover top bar functions anymore.
- Shows unformatted values of x and Last x.
- Long-press to directly call up the register view.
- Correct digit entries by swiping left.
• Email programs directly from the program list
• Replacing registers by pasting a program into the display is now optional
• Support for iOS 13: Dark Mode, file sharing
Check out the new Download walk-through on the website (under "Sharing".)
Bug fix:
• Executing the summation command ∑ with a very large argument would cause a crash
RPN-34 CE now requires iOS 11 or later.
