+   * Test whether a value is NaN (not a number).
+   * The function supports types `number`, `BigNumber`, `Fraction`, `Unit` and `Complex`.
+   *
+   * The function is evaluated element-wise in case of Array or Matrix input.
+   *
+   * Syntax:
+   *
+   *     math.isNaN(x)
+   *
+   * Examples:
+   *
+   *    math.isNaN(3)                     // returns false
+   *    math.isNaN(NaN)                   // returns true
+   *    math.isNaN(0)                     // returns false
+   *    math.isNaN(math.bignumber(NaN))   // returns true
+   *    math.isNaN(math.bignumber(0))     // returns false
+   *    math.isNaN(math.fraction(-2, 5))  // returns false
+   *    math.isNaN('-2')                  // returns false
+   *    math.isNaN([2, 0, -3, NaN])       // returns [false, false, false, true]
+   *
+   * See also:
+   *
+   *    isNumeric, isNegative, isPositive, isZero, isInteger
+   *
+   * @param {number | BigNumber | bigint | Fraction | Unit | Array | Matrix} x  Value to be tested
+   * @return {boolean}  Returns true when `x` is NaN.
+   *                    Throws an error in case of an unknown data type.
