Sum Task

Accepts multiple numerical inputs and returns the sum of them.

Parameters

values: an array of values to sum.
allowedFaults (optional): the maximum number of input tasks that can error without the Sum task erroring. If not specified, this value defaults to N - 1, where N is the number of inputs.

Outputs

The sum of the values in the values array.

Example

my_sum_task [type="sum"
             values=<[ $(fetch1), $(fetch2), $(fetch3) ]>
             allowedFaults=1]

Given the inputs 2, 5, and 20, the task will return 27.
