For the same reason that sqrt() is of type Double in the JPA, pow(decimal, 0.5) is also of type Double. Yes, yes, I know that some dbs (Postgres!) claim that the return type is NUMERIC for NUMERIC arguments. But go on, try it: yes, the return type of typed NUMERIC, but then it has a very suspicious number of digits. Hrrm.... 17 decimal digits, now why does that specific number ring a bell?
