/**
* 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
