Description cinman71481@gmail.com 2024-06-23 07:36:43 UTC 
Kcalc gives me a incorrect awnser whenever I am trying to subtract a number by a percenatge.

Example #1 - 1600 - 20%
Gnome Calculator and Android Calculator = 1280
Kcalc = 1599.8

Example #2 - 1985 - 19.2%
Gnome/Android Calc = 1603.88
Kcalc 1984.808

Example #3 - 2580.25 - 32.98%
Gnome/Android Calc = 1729.28355
Kcalc = 2579.9802

Also different from google calculator, and wolfram alpha. IMO we should be consistent with the major calculators.

The same applies for percentage additions (also in version 24.05.1):
10+20%=10.2 instead of 12
