  /**
   * Round a value towards the nearest integer.
   * For matrices, the function is evaluated element wise.
   *
   * Syntax:
   *
   *    math.round(x)
   *    math.round(x, n)
   *
   * Examples:
   *
   *    math.round(3.22)             // returns number 3
   *    math.round(3.82)             // returns number 4
   *    math.round(-4.2)             // returns number -4
   *    math.round(-4.7)             // returns number -5
   *    math.round(3.22, 1)          // returns number 3.2
   *    math.round(3.88, 1)          // returns number 3.9
   *    math.round(-4.21, 1)         // returns number -4.2
   *    math.round(-4.71, 1)         // returns number -4.7
   *    math.round(math.pi, 3)       // returns number 3.142
   *    math.round(123.45678, 2)     // returns number 123.46
   *
   *    const c = math.complex(3.2, -2.7)
   *    math.round(c)                // returns Complex 3 - 3i
   *
   *    math.round([3.2, 3.8, -4.7]) // returns Array [3, 4, -5]
   *
   * See also:
   *
   *    ceil, fix, floor
   *
   * @param  {number | BigNumber | Fraction | Complex | Array | Matrix} x  Number to be rounded
   * @param  {number | BigNumber | Array} [n=0]                            Number of decimals
   * @return {number | BigNumber | Fraction | Complex | Array | Matrix} Rounded value
