in all normal calaculators, 20% is = 0.20
that is why 100 - 20% => 100-0.20 = 99.8
% is referenced to 1.0 , like for 20 % it is 0.2 and 90% it is 0.90. so that when you do calculation like
25% of amount X , it is going to be X*25% ,
with google and online extra smart calc.
when you say 100 - 20% ,,calc automatically assume that you re asking for 20% of100 , but you never specified that directly .
if you really want to do same with normal calc , it syntax should be 100 - (100*20%) . you have to say of what amount % need tobe substracted.
sony calculator app is fine as it should be , so i think you should get yourself use to it .

@mit_z3plus That's how I also thought things work but it seems calculators assume it's 20% of X if you add or subtract.

I see this is still an ongoing issue. I have a Z5 Compact that used to be ok on Android 5 but when it got the upgrade to Android 6.0 it now cannot do basic subtraction of percentages. When you do 200-15% it shows the result as 199.85 and not 170. It shows RAD in the top left corner. Before the upgrade I used to use it to work ut percentages all the time with no issue or error. Is this a problem with the coding in Android 6, or something else?
