/**
|
|
* 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]
|
|
*

|
* @param {number | BigNumber | Fraction | Complex | Array | Matrix} x Number to be rounded
