    /**
     * Test whether value x is smaller than y.
     *
     * The function returns true when x is smaller than y and 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.
     *
     * Syntax:
     *
     *    math.smaller(x, y)
     *
     * Examples:
     *
     *    math.smaller(2, 3);            // returns true
     *    math.smaller(5, 2 * 2);        // returns false
     *
     *    var a = math.unit('5 cm');
     *    var b = math.unit('2 inch');
     *    math.smaller(a, b);            // returns true
     *
     * See also:
     *
     *    equal, unequal, smallerEq, smaller, smallerEq, compare
     *
     * @param  {number | BigNumber | Fraction | boolean | Unit | string | Array | Matrix} x First value to compare
     * @param  {number | BigNumber | Fraction | boolean | Unit | string | Array | Matrix} y Second value to compare
     * @return {boolean | Array | Matrix} Returns true when the x is smaller than y, else returns false
