# PERCENTILEX.INC

Returns the percentile number of an expression evaluated for each row in a table.

To return the percentile of numbers in a column, use PERCENTILE.INC function (DAX).

## Syntax

```
PERCENTILEX.INC(<table>, <expression>;, k)
```

#### Parameters

Term | Definition |
---|---|

table | The table containing the rows for which the expression will be evaluated. |

expression | The expression to be evaluated for each row of the table. |

k | The desired percentile value in the range 0 to 1 inclusive. |

## Return value

The percentile number of an expression evaluated for each row in a table.

## Remarks

If k is zero or blank, percentile rank of 1/(n - 1) returns the smallest value. If zero, it is out of range and an error is returned.

If k is nonnumeric or outside the range 0 to 1, an error is returned.

If k is not a multiple of 1/(n - 1), PERCENTILEX.EXC will interpolate to determine the value at the k-th percentile.

PERCENTILEX.INC will interpolate when the value for the specified percentile is between two values in the array. If it cannot interpolate for the k percentile specified, an error is returned.
