Implementation Reference
- cruncher.js:1516-1531 (handler)The function that executes the median tool logic: sorts numbers and returns the middle value (or average of two middle values for even-length arrays).
/** * Calculates the median of an array of numbers. * @param {Object} args - The arguments object. * @param {number[]} args.numbers - Array of numbers. * @returns {number} The median value. * @throws {Error} If the array is empty. */ median: ({ numbers }) => { if (numbers.length === 0) throw new Error("Cannot calculate the median of an empty list."); const sorted = [...numbers].sort((a, b) => a - b); const mid = Math.floor(sorted.length / 2); return sorted.length % 2 === 0 ? (sorted[mid - 1] + sorted[mid]) / 2 : sorted[mid]; }, - cruncher.js:585-603 (schema)Input schema for the median tool: requires an array of numbers, with optional custom timeout parameter.
