ABS
The ABS function returns the absolute value of a number.
The schema is SYSIBM.
The argument must be an expression that returns a value of any built-in numeric data type.
The arguments can also be a character string or graphic
string data type. The string input is implicitly cast to a numeric
value of DECFLOAT(34).
The result of the function has the same data type and length attribute as the argument.
The result can be null; if the argument is null, the result is the null value.
ABSVAL can be specified as a synonym for ABS. DB2® supports this keyword to provide compatibility with previous releases.
Example: Assume
that host variable PROFIT is a large integer with a value of -50000.
The following statement returns a large integer with a value of 50000.
SELECT ABS(:PROFIT)
FROM SYSIBM.SYSDUMMY1;
