Sum an array of canonical integer strings and return the canonical total.

Use when you need to: array integer sum · sum integer array · sum canonical integer strings.

Supported

• array integer sum
• sum integer array
• sum canonical integer strings

Not supported

• floating point sum
• mean
• csv column sum
• integer product

Behavior

• Input values is an array of canonical base-10 integer strings with at most 10000 items.
• A canonical integer is 0 or an optional ASCII minus followed by a non-zero leading digit and only digits after that.
• Input -0 is accepted and canonicalized to 0; plus signs, spaces, underscores, hex, exponents, empty strings, and other leading zeros are rejected.
• Each value is parsed with BigInt. IEEE-754 numbers are rejected.
• The empty array sums to 0.
• The output sum is the canonical integer string of the total. Each input and the sum may have at most 1000 digits excluding the sign.

Input

• values (array of string, required): max items 10000; each max length 1001; each pattern ^-?(0|[1-9][0-9]*)$

Output

• sum (string, required): max length 1001; pattern ^(0|-?[1-9][0-9]*)$

Limits

• max items: 10000
• max digits: 1000

Example

Request input:

{
  "values": [
    "19",
    "23"
  ]
}

Response:

{
  "result": {
    "sum": "42"
  }
}
