Calculator of Galaxy S4 shows result of formula using % differently, compared to S3

A : For the Galaxy S4, the concept of '%' in the Calculator feature was changed for usability because most users use '%' for the calculation of interest rates.

If you enter '%' in the previous formula including the number, it will be calculated as a '%' of the previous number.

ex : 10% = 0.1
10+10% = 11 (‘%’ is applied to blue marked 10, so the result value 11 is calculated by 10+10*0.1)
(10+10)+10% = 22 (‘%’ is applied to blue marked 20, so 10% is 20*0.1 )
10+(10+10)+10% = 32 (‘%’ is applied to blue marked 20, so 10% is 20*0.1)

Note : - Parenthesis should be closed automatically when user does not close parenthesis.
- % is the same with “÷100”
