IsaacAsimov Posted May 30, 2012 Share Posted May 30, 2012 Here's a new factorial function I invented that uses the Fibonacci sequence 1,1,2,3,5,... The Fibonacci Factorial, or Fib! is defined as the product of all the Fibonacci numbers up to n. Examples: 1Fib!=1, 2Fib!=1*1*2=2, 3Fib!=1*1*2*3=6, 4Fib!=undefined, 5Fib!=1*1*2*3*5=30 I don't know if this function would be useful for mathematics. Please give me some input.
