Numeric Pair Token Parser

Parse an exact 2-component comma-separated finite numeric token with strict decimal/exponent grammar; no missing components or whitespace.

Description

Parse an exact 2-component comma-separated finite numeric token with strict decimal/exponent grammar; no missing components or whitespace.

A numeric pair token groups two finite values without assigning them an axis or unit.

When to use this tool

Parse an exact 2-component comma-separated finite numeric token with strict decimal/exponent grammar; no missing components or whitespace.

Prepare the supplied token fields for this operation.
Compare the complete example with the representation used by your own input before carrying the result into another step.

How to use the tool and how it works

Enter token. Use the exact text syntax, units and index conventions explained below.
Run the tool. If input validation fails, correct the supplied fields before interpreting any result.
Read result.values. Interpret false, null and empty lists using the distinctions below; they can be valid outputs.

Require token at most 256 UTF-16 code units, split on a comma into exactly two pieces and parse both with the strict decimal/exponent grammar.^[1]

Input field	Meaning and representation	Accepted input
token	token.	Text; at most 8,192 UTF-16 code units, subject to the grammar above

Output field	Interpretation
result	Object containing the named outputs below.
result.values	The values list in the ordering and representation described above.

  "input": {
    "token": "1,-2"
  },
  "output": {
    "result": {
      "values": [
        1,
        -2
      ]
    }
  }
}

Limitations and assumptions

No whitespace trimming, geographic bounds or measurement interpretation is applied.
All declared input fields are required and unexpected top-level fields are rejected. Numbers must be finite; lists are limited to 128 entries and ordinary text fields to 8,192 UTF-16 code units, with tighter limits where stated.
JSON text inputs must parse within bounded nesting and size limits. Numeric outputs outside the safe finite range are rejected; large exact integer results use decimal strings. Indexes and half-open spans are zero-based unless a rank is explicitly described as one-based.

Alternative or Complementary methods

Use a parser for the actual target format when the task requires CSV, shell, URL, calendar or filesystem semantics. These tools implement the specific small grammars stated here, without adding those surrounding conventions.
