Set permissions in binary

Question

I saw in school a system that set permissions using binary string.

Let\'s say 101001 = 41

So :

• 1 can be permission to page 1
• 2 can b

Answer 1

Since it's binary & decimal you can convert it back & forth with decbin and bindec. It's just a different base to count with...

EDIT: bitwise is sweet, do that ^_^
