+   * Test whether two values are equal.
+   *
+   * The function tests whether the relative difference between x and y is
+   * smaller than the configured relTol and absTol. The function cannot be used to
+   * compare values smaller than approximately 2.22e-16.
+   *
+   * For matrices, the function is evaluated element wise.
+   * In case of complex numbers, x.re must equal y.re, and x.im must equal y.im.
+   *
+   * Values `null` and `undefined` are compared strictly, thus `null` is only
+   * equal to `null` and nothing else, and `undefined` is only equal to
+   * `undefined` and nothing else. Strings are compared by their numerical value.
+   *
+   * Syntax:
+   *
+   *    math.equal(x, y)
+   *
+   * Examples:
+   *
+   *    math.equal(2 + 2, 3)         // returns false
+   *    math.equal(2 + 2, 4)         // returns true
+   *
+   *    const a = math.unit('50 cm')
+   *    const b = math.unit('5 m')
+   *    math.equal(a, b)             // returns true
+   *
+   *    const c = [2, 5, 1]
+   *    const d = [2, 7, 1]
+   *
+   *    math.equal(c, d)             // returns [true, false, true]
+   *    math.deepEqual(c, d)         // returns false
+   *
+   *    math.equal("1000", "1e3")    // returns true
+   *    math.equal(0, null)          // returns false
+   *

+   *
+   * @param  {number | BigNumber | bigint | boolean | Complex | Unit | string | Array | Matrix} x First value to compare
+   * @param  {number | BigNumber | bigint | boolean | Complex | Unit | string | Array | Matrix} y Second value to compare
+   * @return {boolean | Array | Matrix} Returns true when the compared values are equal, else returns false
