Ceil Function

In Oracle/PLSQL, the ceil function returns the smallest integer value that is greater than or equal to a number.
The syntax for the ceil function is: ceil( number ) number is the value used to find the smallest integer value.

 For Example
ceil(32.65) would return 33
ceil(32) would return 32
ceil(-32.65) would return -32
ceil(-32) would return -32
