Brackets and parentheses are unnecessary: the user simply performs calculations in the order that is required, letting the automatic stack store intermediate results on the fly for later use.The automatic stack permits the automatic storage of intermediate results for use later: this key feature is what permits RPN calculators to easily evaluate expressions of arbitrary complexity: they do not have limits on the complexity of expression they can evaluate.Thus, expressions are not entered wholesale from right to left but calculated one piece at a time, most efficiently from the center outwards. Calculations occur as soon as an operator is specified.HP-35 version 4 shows correct logo and label at the bottom (on applicable iOS devices.) Version 3 shows the same label as version 2.Simulation of additional known calculation bugs. If audio is playing on start-up, RPN-35 SD will not produce any soundsĢ.Calculator sounds mix with background audio and have their own volume control.Decimal addition/subtraction for higher precision. Improved results for SIN, COS, TAN with very large arguments.Improved trig functions for extremely small angles.Incorrect app icon shown when installed on iPad.Values containing blanks may be pasted into display.Changed "Undo digit" sound to same as found on other CuVee calculators.Simulation of early HP-35 calculation errors.RPN-35 SD now requires iOS 11 or later.HP-35 version 4 shows correct logo and label at the bottom (on applicable iOS devices.).exponent not shown initially, CHS ignored after digit entry, no CHS togglingĢ. Simulation of (rather weird) EEX key behavior, i.e. If RPN-35 is set to HP-35 version v1 ("Red dot") and Vintage Mode is on:ġ.Sweden, Australia, Slovenia) would cause a crash. Calculations in scientific mode in regions not using "E" as exponent symbol (i.e.Optimized Settings View for devices with Home button.Make sure that on your iPhone in "Settings / Sounds & Haptics" the option "System Haptics" is enabled. Set the haptic feedback level in the calculator's settings. STO 0 of value 1939010 x sets haptics level to x (0 = off).Last X operation, performed by entering RCL 0.Addressable registers R1.R9 supporting STO and RCL arithmetic like the HP-45.In this mode, available only if Vintage Mode is off, RPN-35 SD provides advanced register handling. In Vintage Mode, the settings button (wrench) is shown in blue. If HP-35 version 1 is selected, known arithmetic errors are simulated.A keyboard entry or RCL immediately following STO does not raise the stack.A negative number may be entered by pressing CHS before or after the number.Stack register Z gets copied to T on trig functions.In this mode, RPN-35 SD simulates a real HP-35 very closely: Sound Volume: select desired volume of key click.Alternatively, double-tap the display to open the Settings screen. They still work if you tap at the correct position. Hide Extra Buttons: If the Settings and Information buttons are distracting, you may hide them (on devices with a Home button).Key Glow Effect: tapping a key will shortly show a white glow around it.Haptics: select the desired level of haptic feedback when hitting a key.HP-35 Version: select production version 1 ("Red Dot"), versions 2 or 3 (identical apart from the front panel label), or version 4 (with key legends molded into keys).Tap the wrench symbol to access the settings screen: All decimal points but one light up when battery charge drops below 5%.Display stack registers and all memory registers (tap display once).Swipe left across display to correct wrong number entries.Three skins: version 1, versions 2 & 3 (1973) and final version 4 (1974).Despite its steep price of $395 (more than $2,200 today), it sold ten times better than anticipated in the first year. The HP-35 was an immediate hit with students, engineers, and scientists. On January 4, 1972, Hewlett-Packard announced the HP-35, world's first scientific calculator small enough to fit in a pocket - more precisely, Bill Hewlett's shirt-pocket. RPN-35 SD is a photo-realistic simulation of Hewlett-Packard's break-through scientific hand-held calculator.
