SYSIBM.POWER ( EXPRESSION1, EXPRESSION2 ) WILL RETURN INCORRECT RESULTS FOR SOME VALUES WHEN THE BIGINT DATA TYPE IS USED | |
| Produkt: | |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
| Problembeschreibung: | |
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.
values(power(-1,-1), power(bigint(-1),-1), power(-1,bigint(-1)),
power(bigint(-1),bigint(-1)))
