# MAXA Function (DAX)

Returns the largest value in a column. Logical values and blanks are counted.

```
MAXA(<column>)
```

## Parameters

Term

Definition

column

The column in which you want to find the largest value.

## Return Value

A decimal number.

## Remarks

The MAXA function takes as argument a column, and looks for the largest value among the following types of values:

• Numbers

• Dates

• Logical values, such as TRUE and FALSE. Rows that evaluate to TRUE count as 1; rows that evaluate to FALSE count as 0 (zero).

Empty cells are ignored. If the column contains no values that can be used, MAXA returns 0 (zero).

If you do not want to include logical values and blanks as part of the calculation, use the MAX function.

## Example

The following example returns the greatest value from a calculated column, named ResellerMargin, that computes the difference between list price and reseller price.

```=MAXA([ResellerMargin])
```

The following example returns the largest value from a column that contains dates and times. Therefore, this formula gets the most recent transaction date.

```=MAXA([TransactionDate])
```
