Syntax

Read syntax diagramSkip visual syntax diagram CEILCEILING (source_number)

CEIL and CEILING return the smallest integer value greater than or equal to source_number. The parameter can be any numeric data type. The result is of the same type as the parameter unless it is NULL, in which case the result is NULL.

For example: 
CEIL(1)
returns 1 
CEIL(1.2)
returns 2.0 
CEIL(-1.2)
returns -1.0

If possible, the scale is changed to zero. If the result cannot be represented at that scale, it is made sufficiently large to represent the number.
