Recently in Math class I started wondering what would happen if factorials decreased by decimal values instead of by one. So I decided to make a handy-dandy decimal stepping factorial calculator.

Background On Factorials

To find the factorial of any positive integer N, multiply it by each integer less than N and greater than zero.

Stepping By Decimals

Let's define a new operation we'll call the step factorial. For starting number N and stepping number s:

Calculator

Output: 120

Conclusion

Is this useful? Honestly, probably not. I wouldn't be surprised if somebody has done this before. Still, it was a fun little exercise. It's interesting how small changes in s can cause such dramatic shifts in results — play around and see what happens!
