+   * Convert a numeric input to a specific numeric type: number, BigNumber, bigint, or Fraction.
+   *
+   * Syntax:
+   *
+   *    math.numeric(x)
+   *
+   * Examples:
+   *
+   *    math.numeric('4')                           // returns 4
+   *    math.numeric('4', 'number')                 // returns 4
+   *    math.numeric('4', 'bigint')                 // returns 4n
+   *    math.numeric('4', 'BigNumber')              // returns BigNumber 4
+   *    math.numeric('4', 'Fraction')               // returns Fraction 4
+   *    math.numeric(4, 'Fraction')                 // returns Fraction 4
+   *    math.numeric(math.fraction(2, 5), 'number') // returns 0.4
+   *
+   * See also:
+   *
+   *    number, fraction, bignumber, bigint, string, format
+   *
+   * @param {string | number | BigNumber | bigint | Fraction } value
+   *              A numeric value or a string containing a numeric value
+   * @param {string} outputType
+   *              Desired numeric output type.
+   *              Available values: 'number', 'BigNumber', or 'Fraction'
+   * @return {number | BigNumber | bigint | Fraction}
+   *              Returns an instance of the numeric in the requested type
