New extension: Combinatorics

[mcnole25]

This is a basic extension I made to calculate factorials, n choose r, & other stuff like that.

combinatorics.txt

Blocks:
factorial of n: Calculates n factorial: 1 * 2 * 3 * 4 * 5 * ... * n
n choose r permutations: Number of ways to choose elements in a set where order matters
n choose r combinations: Number of ways to choose elements in a set where order DOESN'T matter
n choose r with repeats: Number of ways to choose elements in a set where order DOESN'T matter, but repeated elements are allowed

Repeated permutations are excluded, because the formula is simply n**r

It's been about a year since I used Scratch or Turbowarp, or even made an extension. Enjoy.

NOTE: This extension is in beta, inputs break after 170, I plan to polish this in the future

I recommend using BigInt-type numbers only if decimals don't matter.
With BigInt, you can calculate the factorial of 200,000, and I know BigInt can do more.
