Ceiling function

Revision as of 11:26, 29 June 2006 by JBL (talk | contribs)

The ceiling function, also known as the least integer function, gives the least integer greater than or equal to its argument. The ceiling of $x$ is usually denoted by $\lceil x \rceil$.

For an example:

$\lceil 4.5 \rceil$ = 5

$\lceil -e \rceil$ = -2
