It's code of mine if u wanna take a look it's pretty messy

Answer 2

Lets check mine. The code is compact but very powerfull.
Supported operations are + - * / %, bitwise & ^ |, power #.
Parathneses are supported. Operations priority are supported.

Input like: -5*3 + 2#4/(3+2*-3+2*(2+4))

Answer 3

the Power Calculator can manage the expressions like 3 * -(2+1) with result of -9. And the previous one can’t

Answer 4

Jegors Čemisovs 2^(3*2) = 4 is false check this out

Answer 5

You are right. I’ve use ^ as original Java bitwise operator and this is confusing. You thinking that this is a 2 power 6 but this is 2 xor 6 and 2 xor 6 == 4
