I was looking at a small example program that calculates Fibonacci numbers to use as output.

Fibonacci Numbers: A sequence of numbers where each subsequent number is calculated by obtaining the sum of the previous two numbers. ie... 1,1,2,3,5,8,13,21.....

So i take it that Fibonacci is some old Itialian mathematician. But what is the point of this sequence? What could or has it ever been used for?


Thanks
