Function ceil #
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)
math.ceil(unit, valuelessUnit)
math.ceil(unit, n, valuelessUnit)

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
const unit = math.unit('3.241 cm')
const cm = math.unit('cm')
const mm = math.unit('mm')
math.ceil(unit, 1, cm) // returns Unit 3.3 cm
math.ceil(unit, 1, mm) // returns Unit 32.5 mm
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]
