CEIL()
Description
The CEIL(X) function returns the smallest integer value not less than X.
Syntax
1. > CEIL(X)
Arguments
| Arguments | Description |
|---|---|
| X | Required. Any numeric data type supported now. |
For exact-value numeric arguments, the return value has an exact-value numeric type. For floating-point arguments, the return value has a floating-point type.
Examples
1. > drop table if exists t1;
2. > create table t1(a int ,b float);
3. > insert into t1 values(1,0.5);
4. > insert into t1 values(2,0.499);
5. > insert into t1 values(3,0.501);
6. > insert into t1 values(4,20.5);
7. > insert into t1 values(5,20.499);
8. > insert into t1 values(6,13.500);
9. > insert into t1 values(7,-0.500);
10. > insert into t1 values(8,-0.499);
11. > insert into t1 values(9,-0.501);
12. > insert into t1 values(10,-20.499);
13. > insert into t1 values(11,-20.500);
14. > insert into t1 values(12,-13.500);
15. > select a,ceil(b) from t1;
