percent button (%) may be faulty

[cuter-doc0]

Behaviourally, the percent button doesn't work as it does on iOS. An issue seen when trying:

• 100 (x) 35 (%) (=) is that the calculator shows 0.35 x 0.35 = 0.1225 whereas on iOS or MacOS the same sequence of buttons will return the value "35"
• 100 (+) 35 (%) (=) will result in an output of 35 + 35 = 70 whereas on iOS or MacOS the same sequence of buttons will return the value "135"
