The "+/-" key does not work as a unary operator to change sign. Therefore, to enter the same number, you have to either type in the number again, or use "dup" function. Repeating ENTERs does not push the x register into stack. (To do this right, you have to do "2 ENTER 3-", or "2 ENTER 3 ENTER sub".) Therefore, you cannot do "2 ENTER 3 ENTER -" for 2-3, while you can do "2 ENTER 3 ENTER +" for 2+3. "-" is treated both as a prefix for a negative number and a "minus" operator. 
You type functions, and it is faster than using a mouse. All you see is an entry field and the last 3 levels of stack. 
Even for simple arithmetic, you have to use a mouse. The keyboard shortcuts only correspond to the position of the buttons, instead of their function names. The precision can be set to many digits. There is no "E" key to key in in an exponent format like 1.2E3. Invalid input pushes buttons away from the calculator, and sometimes it takes other operations to restore them. If you enter numbers by both buttons and keyboard, the cursor hangs at a wierd position. It has descent decent shortcut keys, as "s = sin, shift/s = asin. Complex number calculation is not as simple as RPN 1.96. To let PCalc behave as HP calculators, you should press "C" button or its keyboard shortcut, "esc" key. "Delete" key on PCalc drops y-register (01:) to x-register, and replaces 1 with 2. For example, on HP calculators, 1 ENTER <- 2 puts 1 in y-register and 2 in x-register. However, once "ENTER" key is pressed, it behaves differently. While keying in numbers, it behaves like HP's "< -" key, which deletes the last digit. The function of "Delete" key is confusing. Keyboard shortcuts are not available for many of the common scienfic functions. It lacks "Last x" key, but command-z will undo the last operation. It handles hex/oct/bin mode and their bitwise logical operators. Not many keyboard shortcuts are available. On PowerBook G4 (800MHz), the "+", "-" and "*" keys do not work as keyboard shortcuts. 4.0 had a serioius bug Typing "C 1 EE 0 enter" caused an error, but it is fixed on v4.0.4 that came with OS X 10.3.4. Programmer mode has unusual "Byte Flip" and "Word Flip" buttons. It has three modes, basic, scientific, and programmer. Hp48 emulator mac mac os x#
(But I will forgive this).Ĭalculator 4.0.4 included in Mac OS X 10.4 Tiger ***Ī normal looking calculator turns into RPN mode by selecting the option. Cannot enter octal/hexadecimal numbers directly.With extensive keyboard shortcuts, it can work even without showing keys. It occupies small area on the desk top.Standard/Scientific/Engineering display modes are available.Well thought-out keyboard shortcuts allow you to calculate without using a mouse.In RPL, this is not the case, so you have to do 2 ENTER ENTER sin +.įor more details, take a look at Museum of HP calculators. For example, to calculate 2 + sin(2), in RPN, you do 2 ENTER sin + because you will have '2' in both x and y registers after hitting ENTER. If you are familiar with old HP calculators using RPN, you might get confused a little with RPL. You can also enter a number followed by an operator. The "ENTER" key copies the contents of the input buffer into x-register. With RPL, the number you enter goes into an input buffer first. HP calculators like HP35, HP25, HP15, HP32S, HP42S, etc. The "ENTER" key copies the contents of the x-register into the next y-register. With RPN, the number you enter goes into the bottom of the stack (x-register for HP calculators). There are mainly two kinds of reverse polish styles, RPN and RPL. In addition, the calculators should have basic keyboard shortcuts for a quick entry. Therefore, one of the criterias for the star ratings below is based on how close the calculators behave as HP calculators. I have been using HP calculators, and so must be many of the people who are looking for RPN calculators on Mac OSX.
