CEIL
CEIL determines the smallest integer value greater than or equal to x, and assigns this value to the result.
- x
- Real expression.
The result has the mode, base, scale, and precision of x,
except when x is fixed-point with precision
(p,q). The precision of the result is then
given by:
(min(N,max(p-q+1,1)),0)
where
N is the maximum number of digits allowed.
