Function Ceil(x)


    x             ! (input) numerical expression



A scalar numerical expression.

Return Value

The function Ceil returns the smallest integer value \(\geq\) x.


  • The function Ceil will round to the nearest integer, if it lies within the equality tolerances equality_absolute_tolerance and equality_relative_tolerance.

  • The function Ceil can be used in the constraints of nonlinear mathematical programs. However, nonlinear solvers may experience convergence problems around integer values.

  • When the numerical expression contains a unit, the function Ceil will first convert the expression to the corresponding base unit, before evaluating the function itself.
