Table 2.10 Mathematical Functions

Name	Description
ABS()	Return the absolute value.
ACOS()	Return the arc cosine.
ASIN()	Return the arc sine.
ATAN()	Return the arc tangent.
ATAN2(), ATAN()	Return the arc tangent of the two arguments
CEIL()	Return the smallest integer value not less than the argument. The function is not applied to BIGINT values. The input value is returned. CEIL() is a synonym for CEILING().
CEILING()	Return the smallest integer value not less than the argument. The function is not applied to BIGINT values. The input value is returned. CEILING() is a synonym for CEIL().
COS()	Return the cosine.
