I see there are some tests in src/test/regress: sql/numeric.sql expected/numeric.out
They pass. I see "numeric ... ok" in a make check. I do not doubt they are being run, because if I edit numeric.sql and fudge some digits, say around -- cases that used to error out select 0.12 ^ (-25); select 0.5678 ^ (-85); and I change the -25 to -26, numeric then fails in my next make check. All that seems just as it should be. Why, then, if I try to duplicate those exact tests in an interactive session, would this happen: postgres=# select 0.12 ^ (-25); ERROR: division by zero STATEMENT: select 0.12 ^ (-25); postgres=# select 0.5678 ^ (-85); ERROR: division by zero STATEMENT: select 0.5678 ^ (-85); ... they error out, that is, do exactly the thing the tests are there to make sure they do not. Is there some special GUC setting in effect during the make check that would be different in my ordinary session? What else could be different? This is making me question my sanity. -Chap
