PERMUT(n,nc)

• $n$ and $nc$ 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 $PERMUT(n,nc),n$ 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:<math>n P_k= \frac {n!}{(n-k)!}
• The Permutation is denoted by nPk, Pn,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

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