# SUM

This function returns the sum of cells or range of cells.

## Syntax

`SUM(value1, value2,...)`

`SUM(array)`

`SUM(array1, array2,...)`

## Arguments

Each argument can be a double-precision floating-point value, an integer value, or an array (cell range) of these. Up to 255 arguments may be included.

You can use a single array (cell range) instead of a list of values.

You can use multiple arrays (cell ranges) as well.

## Remarks

Range references with mixed relativeness for column or row endpoints are not supported with the SUM function. R1C:R2C is okay but, R1C1:R2C is not.

The SUM function ignores non-numeric values passed by reference. For example, if A1 contains TRUE, A2 contains "2", and A3 contains 4, then:

`TRUE+"2"+4` evaluates to 7

`A1+A2+A3` evaluates to 7

`SUM(TRUE,"2",4)` evaluates to 7

`SUM(A1,A2,A3)` evaluates to 4

The + operator provides an auto-conversion for non-numeric values passed by constant and for non-numeric values passed by reference. The SUM function provides an auto-conversion for non-numeric values passed by constant but, ignores non-numeric values passed by reference.

## Data Types

Accepts numeric data for all arguments. Returns numeric data.

## Examples

`SUM(A1,B7,C11)`

`SUM(A1:A9)`

`SUM(A2:A14,B2:B18,D12:D30)`

`SUM(R1C2,R3C5,R6C2,R1C7)`

`SUM(95,89,73,87,85,76,100,96,96)` gives the result 797
