  /**
   * Compare two values. Returns 1 when x > y, -1 when x < y, and 0 when x == y.
   *
   * x and y are considered equal when the relative difference between x and y
   * is smaller than the configured epsilon. The function cannot be used to
   * compare values smaller than approximately 2.22e-16.
   *
   * For matrices, the function is evaluated element wise.
   * Strings are compared by their numerical value.
   *
   * Syntax:
   *
   *    math.compare(x, y)
   *
   * Examples:
   *
   *    math.compare(6, 1)           // returns 1
   *    math.compare(2, 3)           // returns -1
   *    math.compare(7, 7)           // returns 0
   *    math.compare('10', '2')      // returns 1
   *    math.compare('1000', '1e3')  // returns 0
   *
   *    const a = math.unit('5 cm')
   *    const b = math.unit('40 mm')
   *    math.compare(a, b)           // returns 1
   *
   *    math.compare(2, [1, 2, 3])   // returns [1, 0, -1]
   *
   * See also:
   *
   *    equal, unequal, smaller, smallerEq, larger, largerEq, compareNatural, compareText
   *
   * @param  {number | BigNumber | Fraction | Unit | string | Array | Matrix} x First value to compare
   * @param  {number | BigNumber | Fraction | Unit | string | Array | Matrix} y Second value to compare
   * @return {number | BigNumber | Fraction | Array | Matrix} Returns the result of the comparison:
   *                                                          1 when x > y, -1 when x < y, and 0 when x == y.
