Q: Why not use UInt64 as return type for the function. It should be the same on all platforms.
Remark: it seems a bit strange to me to derive Lucas(n) from Fib(n), because the Fibonacci sequence is jus a special case of the Lucas numbers (with starting values 1,1). --Bart (talk) 19:15, 10 November 2018 (CET)
