Array integer mode

array-integer-mode · version 1.0.0 · Numbers & math · free, no key needed

Return the most frequent canonical integers, listing every mode in first-seen order.

Use when you need to: array integer mode · mode of integer strings · most frequent integers.

Supported

• array integer mode
• mode of integer strings
• most frequent integers

Not supported

• kernel density
• fuzzy clustering
• mean of integers
• CSV column mode

Behavior

• values is a non-empty array of at most 10000 canonical integer strings (BigInt; -0 becomes 0).
• Frequencies are counted on canonical integer values, not original spellings.
• count is the maximum frequency as a JSON integer.
• modes lists every canonical value that occurs count times, in first-seen order.
• If every value is unique, every value is a mode and count is 1.

Input

• values (array of string, required): min items 1; max items 10000; each min length 1; each max length 1001

Output

• modes (array of string, required): min items 1; max items 10000; each pattern ^(0|-?[1-9][0-9]*)$
• count (integer, required): min 1; max 10000

Limits

• max values: 10000
• max digits: 1000

Example

Request input:

{
  "values": [
    "2",
    "1",
    "2",
    "3",
    "1",
    "2"
  ]
}

Response:

{
  "result": {
    "modes": [
      "2"
    ],
    "count": 3
  }
}
