SUM Function
The SUM function calculates the sum of a range of cell values. An optional constant may be added to sum all cells in a specific increment. If no constant is supplied, an increment of one is assumed.
Syntax
SUM(cell number..cell number<,constant<,argument>>)
The constant specifies if any cells should not be included. If no value is entered, the default constant is 1 (include all).
The argument is optional and controls which cells are summed. If no argument is specified, the function sums the contents of all cells in the range.
|
Argument |
Result |
|
0 |
The function returns a count of all cells in the range. |
|
1 |
The function returns a count of cells in the range that have a non-zero value. |
|
2 |
The function returns the sum of all cells in the range with positive values. |
|
3 |
The function returns the sum of all cells in the range with negative values. |
A cell with a zero value is a cell that is empty or that contains a blank.
Note: If an argument is used then a constant must be specified.
Example 1
SUM(c1..c9)
Returns the sum of all cells numbered c1 to c9.
Example 2
SUM(c2..c10,2)
Returns the sum of cells numbered c2, c4, c6, c8, and c10.
Example 3
SUM(c2..c10,1,1)
Returns the count of all non-zero value cells in the range c2 to c10.
Note
- If inserting a row between the last entry in the sum calculation and sum row, the sum calculation automatically updates for the new row added. For example, if the cells look like this:
A1
A2
sum(a1..a2)
adding a row between A2 and the sum changes the sum to sum(a1..a3). However, adding a row only updates the summation if the row above the inserted row was actually included in the sum. For example, if the cells look like this:
A1
A2
A3
sum(a1..a2)
adding a row between A2 and the sum does not update the sum.
Likewise, deleting a row from a summed group of cells updates the sum as well. If the cells look like this:
A1
A2
A3
sum(a1..a3)
deleting row A3 will update the sum to sum(A1..A2)
