+   * Test whether a value is an integer number.
+   * The function supports `number`, `BigNumber`, and `Fraction`.
+   *
+   * The function is evaluated element-wise in case of Array or Matrix input.
+   *
+   * Syntax:
+   *
+   *     math.isInteger(x)
+   *
+   * Examples:
+   *
+   *    math.isInteger(2)                     // returns true
+   *    math.isInteger(0)                     // returns true
+   *    math.isInteger(0.5)                   // returns false
+   *    math.isInteger(math.bignumber(500))   // returns true
+   *    math.isInteger(math.fraction(4))      // returns true
+   *    math.isInteger('3')                   // returns true
+   *    math.isInteger([3, 0.5, -2])          // returns [true, false, true]
+   *    math.isInteger(math.complex('2-4i'))  // throws an error
+   *
+   * See also:
+   *
+   *    isNumeric, isPositive, isNegative, isZero
+   *
+   * @param {number | BigNumber | bigint | Fraction | Array | Matrix} x   Value to be tested
+   * @return {boolean}  Returns true when `x` contains a numeric, integer value.
+   *                    Throws an error in case of an unknown data type.
