Tons of features, but in pure calculator mode for every day, we stay away from the effectiveness of HP 15C and HP 32S II or HP 35S. RPN is not widespread and no longer follows all the principles of HP RPN calculators old. So a star less ... (To be precise, for connoisseurs, ENTER, normally used only to separate the entry of two numbers is not based on this principle, making it less effective calculations in everyday life. For Example 5 ENTER * no longer 25 ... ENTER copy the input line in the stack, and thus 5 ENTER ENTER * 4 gives 20. Just as 5 ENTER * 4 gives 20 as well ... The entry line is really the first stack level ... And we have much less access functions directly, such as%,% CHG for example. Another example is the exchange of the first stack level 2, to the division in the common sense example, requires ENTER too. Where we typed 2 XY / 2 for calculating / (previous result), here it is necessary to 2 XY ENTER (button,) / ... Because the line Input is not a stack level, and press XY when entering a number adds a comma ...
By cons, there are the calculations on complex matrices, computer algebra, ... short tons of advanced features.
But for everyday calculations, it is not a panacea ...
