>The others gave you the number answer; to calculate this, you would solve for n in the below formula:
>
>2**n = 2,147,483,647
>LOG(2**n) = LOG(2,147,483,647) ; take the log value of both sides of the equation
>n*LOG(2) = LOG(2,147,483,647) ; the power can be moved to be multiplied as shown
>n = LOG(2,147,483,647) / LOG(2) ; now divide each side by LOG(2)
>n = 30.999999999\
>
>2**31 equals 2,147,483,648; so any number less than the power of 2**31 could be stored; or the maximum int power is 30.

Thank you.
