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

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}**.
