What is the Fibonacci Sequence? The Fibonacci Sequence is a sequence of numbers that begins with 1, 1, and every number after that is the sum of the two numbers before it. What does this program do? This program calculates the first 1,476 numbers of the Fibonacci Sequence. Unfortunately, it can't go past that, because then Scratch will just start saying "Infinity" instead of actually calculating it - which makes sense, considering just how mind-bogglingly big the numbers are at that point. What do the numbers written like "1.5005e+21" mean? This is scientific notation, and you'll notice that it occurs after the first 102 numbers. The 1.5005 is the base number, and the e+21 means 10 to the 21'st power - 1000000000000000000000. Numbers written this way can be calculated by multiplying the base number by 10^21, but you will end up with something that looks a little bit like this: 1500500000000000000000. The last number this program calculates, 1.3069892237633987e+308, comes out to 130698922376339870000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000!
