Description
allRPNCalc is a versatile calculator that uses the powerful Reverse Polish Notation logic system combined with an automated 4 level stack to compute answers to complex mathematical problems. The keyboard layout and display have been optimized for use on an iPhone,iPod Touch and iPad. Large keys with sound feed back give you typing confidence and the last function keyed is always displayed. Functions are logically laid out to eliminate multiple key entry for most problems.
Display: Results are displayed in fixed, fraction, scientific or engineering notation with from 0 to 14 significant digits displayed. In programmer’s mode hex, decimal, octal or binary (with windowing) can be displayed. Calculations are carried out in industry standard IEEE double format with 14+ significant digits and exponents ranging +/-308.
Math: +, -, ×, ÷, ln, log, e^x, 10^x, y^x, x², x³, 1/x, √x, ∛x, fraction part, integer part, absolute value, random, seed, mod
Trigonometry: sin, cos, tan, asin, acos, atan, sinh, cosh, tanh, asinh, acosh, atanh, to radians, to degrees, to rectangular, to polar, to hours, to hours minutes seconds, hours minutes seconds add and subtract, triangle solver, π, π/2. Trig functions can be computed in radians, degrees or gradians.
Statistics: sum plus, sum minus, mean, weighted mean, standard deviation, population standard deviation, linear estimate x, y and correlation coefficient, combination, permutation, factorial (gamma), percent, delta percent, percent of total
Programer’s functions: and, or, xor, not, shift left, shift right, rotate left, rotate right, word sizes 8, 16, 32, 48
Conversions: 47 world currencies and over 100 commonly used metric, english and other conversion factors used in scientific, engineering and financial calculations.
Financial: time value of money calculations, n, i, pv, pmt, fv, depreciation (straight line, sum-of-years, declining balance), bond price and yield to maturity, amortization, net present value, internal rate of return, up to 80 cash flows, days between dates, date plus days, rounding.
Storage: 4 level automatic stack with lastX, exchange and roll down, 20 general purpose storage registers, register arithmetic +,-,×,÷ , 6 dedicated registers for statistics, 80 cash flow entries, 5 financial registers.

Ratings and Reviews
great app - just what I needed
this does everything well, providing you do not want graphing.
great finance stats and conversions.
easy to use
the best app I have bought.
Still the best RPN calculator
Version 3 has added features; it is just as stable--perfectly stable; never crashes, no problems--as the earlier versions. A great application in every way and a bargain compared to any other RPN calculator in the App Store or stand-alone.
My "go-to" calculator!
This has been my calculator since I first switched from a Palm TX to an iPhone (long, sad story). I have bought a couple of HP emulators which I still use when nostalgia gets the better of me, but this calculator is still the one I use on a daily basis - it's got it all and goes beyond anything my beloved HPs could possibly deliver, even with all the program packs on the planet…
This latest version is (on reflection) an improvement. I'm finding myself miskeying far less often (always a problem with glass keyboards), and the few changes actually work quite well once you get used to them. If you want a do-it-all RPN calculator, give this one a try. It's well worth it.
( Now 25/5/2018 and I wouldn't change a word of the above review!)
(Now 3/8/2019 and I wouldn’t be without this app!)
