Type Description
number | BigNumber | Fraction | Complex | Array | Matrix Rounded value

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

const c = math.complex(3.2, -2.7)
math.ceil(c)                 // returns Complex 4 - 2i

math.ceil([3.2, 3.8, -4.7])  // returns Array [4, 4, -4]
