Julia power operator not working as expected

I'm just experimenting with Julia and found that it gives incorrect value when run:

Input:

println(1000^6)
println(1000^7)
println(1000^8)
println(1000^9)

Output:

1000000000000000000
3875820019684212736
2003764205206896640
-6930898827444486144

Is this an issue or am I doing it wrong?

As explained the problem is due to integer overflow. Maximum value you can store in an Int64 can be obtained thanks to 

julia> typemax(Int64)
9223372036854775807

However, 1000^9 is bigger, as you can see with:

julia> BigInt(1000)^9
1000000000000000000000000000
