Math: sum

Calculate the total addition of numbers. Inputs can be Numbers or Arrays of numbers — nested arrays are recursively flattened and summed. If no input values are received, the output is the Initial value (default 0).

Example

# Example with no initial value:
Input: [1, 2, 3, 4]
Ouput: 10

# Example with initial value = 10:
Input: [1, 2, 3, 4]
Ouput: 20

# Example with nested arrays:
Input: [1, [2, [3, 4]]]
Ouput: 10

# Example with no input and initial value = 5:
Ouput: 5

Parameters

Initial value

Constant added to the sum of the inputs. Defaults to 0 when left empty.

Input

Number (multiple)required

Numbers or Arrays of numbers. Arrays (including nested ones) are recursively flattened and their elements summed. When nothing is wired or no values arrive, the output is just the Initial value.

Output

Number

Result of the addition (sum of all inputs plus the Initial value).
