The PERMUTATIONA function returns the number of permutations for selecting a group of objects (with replacement) from a total number of objects. Mathematically, it is equivalent to raising the total number of objects to the number of objects being chosen.
Parts of a PERMUTATIONA function
PERMUTATIONA(number, number_chosen)
| Part | Description |
number |
Required. The total number of objects to choose from. |
number_chosen |
Required. The number of objects to choose from number. Must be less than or equal to number. |
Notes
- Both arguments are truncated to integers.
- If the number is zero,
PERMUTATIONAreturns a #NUM.
Examples
Result for A1=PERMUTATIONA(3, 2), A2=PERMUTATIONA(3.2, 2), A3= PERMUTATIONA(3, 2.4).
Note: All functions return the same result due to truncation.
| A | B | |
| 1 | PERMUTATIONA | Formula |
| 2 | 99 | =PERMUTATIONA(3, 2) |
| 3 | 9 | |
| 4 | 9 | =PERMUTATIONA(3.2, 2.3) |
