About RPN-32 CE
RPN-32 CE is the first photo-realistic simulation of Hewlett-Packard's popular mid-range scientific calculator HP-32E for the iPhone. Produced from 1978 through 1983, it was the "Thyme" member of the third-generation HP calculators known as the "Spice" series.
While the simulator works like the original calculator, a number of carefully designed extensions make it a lot easier to use.
Unlike the HP-32E, this version is fully programmable, running virtually all programs written for the HP-25!
Features:
• Photo-realistic look-and-feel
• Programmable (99 steps), subroutines, flags, loop control, branching
• Insert and delete steps with automatic address correction
• 20 registers, "continuous", with unrestricted store/recall arithmetic
• Indirect register addressing
• "Live" register view
• Program listing view
• Program library view
• Store and retrieve any number of programs
• Sharing: e-mail, AirDrop, Dropbox, copy, paste, print
• 44 programs pre-installed
• Import GO-25 programs
• Export programs to RPN-25 CE
Calculator functions:
• Statistics (mean, standard deviation, linear regression, normal distribution)
• Factorial
• Trigonometric functions (degrees, radians, grads)
• Polar/rectangular conversions
• Hyperbolics
• Inverse, square root, logarithm, exponential, pi
• Storage arithmetic (store and recall)
• Percent change
• Percentage of Total
• Unit and hours conversions
• Many additional functions not found on the HP-32

Enjoy a major new release:
• Real subroutines with GSB and RTN, 4 levels of nesting
• Loop control via register R.9 (DSE, ISG)
- Store control value nnnnn.xxxyy in R.9, where
nnnnn = counter
xxx = limit to test (default 0)
yy = increment/decrement value (default 1)
DSE: decrement nnnnn by yy and skip step if nnnnn ≤ xxx
ISG: increment nnnnn by yy and skip step if nnnnn > xxx
• 10 flags F0…9:
- F? n Test flag n
- SF n Set flag n
- CF n Clear flag n
F2 auto-clears on test
F3 auto-sets on numeric input, clears on test
CLEAR ALL clears all flags
