DB2 FOR LUW / DB2FORLUW / A10 - DB2

The POWER scalar function will return incorrect results for 
certain values if at least one BIGINT argument is used. 
 
The following is a list of values that will produce incorrect 
results: 
 
Case (1) Argument 1 is 2 or -2 and argument 2 is -1.  The 
correct result is to be 1 if argument 1 is 2 and -1 if argument 
1 is -2, but 0 is returned instead. 
 
Case (2) Argument 1 is -1 and argument 2 is less than 0.  The 
correct result is to be -1 if argument 2 is odd and 1 if 
argument 2 is even, but 0 is returned instead. 
 
Case (3) Arguments 1 and 2 are both 0.  The correct result is 1, 
but an overflow error (SQL0802N; SQLSTATE=22003) is returned 
instead. 
 
For example, the value in each column should be -1, but instead 
the value in columns 2, 3, and 4 is 0.
