  /**
   * 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.
   * Strings are compared by their numerical value.
   *
   * Syntax:
   *
   *    math.smaller(x, y)
   *
   * Examples:
   *
   *    math.smaller(2, 3)            // returns true
   *    math.smaller(5, 2 * 2)        // returns false
   *
   *    const a = math.unit('5 cm')
   *    const 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
