The CEIL function returns the smallest integer that is not less than its argument. The return value is determined based on the valid number of digits that are specified as the number_operand argument.
CEIL( number_operand )
SELECT CEIL(34567.34567), CEIL(-34567.34567);
ceil(34567.34567) ceil(-34567.34567)
============================================
34568.00000 -34567.00000
SELECT CEIL(34567.1), CEIL(-34567.1);
ceil(34567.1) ceil(-34567.1)
=============================
