Ceiling function

Revision as of 07:03, 24 June 2006 by Solafidefarms (talk | contribs) (Least integer function moved to Ceiling: Ceiling is more modern.)

The least integer function, or the ceiling function, finds the least integer greater than or equal to its argument. The ceiling of $x$ is often denoted by $\lceil x \rceil$.

For an example:

$\lceil 4.5 \rceil$ = 5

$\lceil -e \rceil$ = -2
