PERMUT
Returns the number of permutations for a given number of objects.
Syntax:
PERMUT(n; k)
- where n and k are integers.
- PERMUT returns the number of ordered ways that k objects can be chosen from a set of n objects, where an object can only be chosen once. For example with a set of 3 objects A, B, C, we can choose 2 as follows: AB, AC, BA, BC, CA, CB.
- PERMUT calculates:
Example:
PERMUT(3; 2)
- returns 6, as in the example above.
See also:
Issues:
- The forthcoming international standard ODFF expects n and k to be integers. Both Calc and Excel truncate any non-integer parameter.
