**PERMUT(n,nc)**

- and are integers

## Description

- This function gives the number of Permutations for a given number of objects.
- A permutation, also called an "arrangement number" or "order," is a rearrangement of the elements of an ordered list.
- A selection of objects in which the order of the objects matters.
- A Permutation is an ordered Combination.
- In is an integer which is indicating the number of objects and nc is an integer which is indicating the number of objects in each permutation.
- For n and nc ,when we are giving in to decimals it will change in to integers.
- The formula for the number of permutation is:
- The Permutation is denoted by _nP_k, P_{n,k}, or P(n,k).This function will give the result as error when

1.n and nc are nonnumeric. 2.Suppose n<=0 or nc<0 or n<nc.

## Examples

- PERMUT(14,2)=182
- PERMUT(50,5)=254251200
- PERMUT(10.2,3)=720
- PERMUT(4,0)=1
- PERMUT(6,1)=6
