/**
* Round a value towards plus infinity
* If `x` is complex, both real and imaginary part are rounded towards plus infinity.
* For matrices, the function is evaluated element wise.
*
* Syntax:
*
* math.ceil(x)
* math.ceil(x, n)
*
* Examples:
*
* math.ceil(3.2) // returns number 4
* math.ceil(3.8) // returns number 4
* math.ceil(-4.2) // returns number -4
* math.ceil(-4.7) // returns number -4
*
* math.ceil(3.212, 2) // returns number 3.22
* math.ceil(3.288, 2) // returns number 3.29
* math.ceil(-4.212, 2) // returns number -4.21
* math.ceil(-4.782, 2) // returns number -4.78
*
* const c = math.complex(3.24, -2.71)
* math.ceil(c) // returns Complex 4 - 2i
* math.ceil(c, 1) // returns Complex 3.3 - 2.7i
*
* math.ceil([3.2, 3.8, -4.7]) // returns Array [4, 4, -4]
* math.ceil([3.21, 3.82, -4.71], 1) // returns Array [3.3, 3.9, -4.7]
*
* See also:
*
* floor, fix, round
*
* @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
