What does the vertical pipe slash operator do?
6
I'm wondering what pipe slash |/ does in,
SET equal_area_radius = |/area/pi();
The statement works and it definitely changes the value:
wrk=# select ( |/125.555/pi() );
?column?
------------------
6.32181918120139
(1 row)
wrk=# select ( 125.555/pi() );
?column?
------------------
39.9653977598058
(1 row)
What does the pipe-slash operator |/ do?
postgresql operator

The |/ operator calculates the square root
postgres> select |/16, sqrt(16);
?column? | sqrt
----------+------
4 | 4
(1 row)
So |/125.555/pi() is equivalent to sqrt(125.555/pi())

Sure enough--looked at the site where I copied the statement from and they had this: i.imgur.com/5twDykK.png I should have worked that one out. Thanks!
