fx-CG50 Result to Percent


Best Answer MJim , 16 January 2020 - 04:45 AM

From what I can tell, you can't do percentage calculations on the fx-CG50, at least not the typical percentage calculations.

 

The fx-991EX you also have though will do these (check out page 11 on the fx-991EX manual under the heading "Percent Calcuations").

 

By the way, you can use Shift4 to access the complete catalog of all the functions on the fx-CG50.  To find a function, type the name of the function you wish to find (use the letters indicated pink on the calculator). 

 

There is a "Percent" function, but what it does is takes a list of numbers and returns another list with the % each value represents of the sum of that list (note: these are special curly brackets that are used to contain lists of numbers):

 

Percent {5, 20}

{20,80}

 

In this example the total of the list is 25.  5 represents 20% of the total value, while 20 represents 80% of the total value, which is shown by the list returned: {20,80}.

If I have a result of 0.00626702997 and want that as a percent what do I press?

Thank you. It is strange that the more expensive model does not and the less expensive model does. I am still getting to know both models but I did notice that the fx-991EX seems to do more overall day to day things. Also less button presses in some cases.

The Casio graphing calculators are really good (The fx-9750G2 really helped me through some material mechanical stress/strain problems with it's large matrices), but some of the basic functionality (eg Engineering symbols, rectangular/polar conversions, probability, etc) are hidden away in menus, making certain quick calculations a bit tedious.

 

Haiving the fx-991EX or something similar as a complement to a Casio graphing calculator I think is a good idea.  So far, my fx-991W fufills this role; it's fairly compact and has a decent keyboard layout.  It's missing all the equation/matrix/vector functionality, but I find that is better done on the Casio graphing calculators like the fx-9750G2 or fx-CG50 anyway.
