Description of ceil.gif follows
Description of the illustration ceil.gif


CEIL returns the smallest integer that is greater than or equal to n. The number n can always be written as the difference of an integer k and a positive fraction f such that 0 <= f < 1 and n = k - f. The value of CEIL is the integer k. Thus, the value of CEIL is n itself if and only if n is precisely an integer.

This function takes as an argument any numeric data type or any nonnumeric data type that can be implicitly converted to a numeric data type. The function returns the same data type as the numeric data type of the argument.

The following example returns the smallest integer greater than or equal to the order total of a specified order:

SELECT order_total, CEIL(order_total)
  FROM orders
  WHERE order_id = 2434;
