Hm, it won't help your sanity to know that those cases pass fine for me, interactively, on a couple of different machines: $ psql postgres psql (11devel) Type "help" for help. postgres=# select 0.12 ^ (-25); ?column? ------------------------------------------- 104825960103961013959336.4983657883169110 (1 row) postgres=# select 0.5678 ^ (-85); ?column? ---------------------------------------- 782333637740774446257.7719390061997396 (1 row) You sure you're using a stock build of Postgres? No handmade versions of operator ^ lying around? regards, tom lane
