Thanks!

Thanks, Jonathan

Didn't see whom to contact on the PG-Pages, but wanted to help.

Cheers, P

Not a problem! I wanted to make sure the correct people saw it :-)

Jonathan

AFAICS, those examples refer to -43.8 not 43.8, and are quite correct.

Thanks, Tom.

Can confirm this. My error was that examples for "round" are using 
positive values and examples of "ceiling"/"floor" are using negative 
ones. Maybe misleading on a fast look.

Sorry for wasting your time, guys!

Patrick

Dear PostgreSQL developers and webmasters

It appears that the documentation of the mathematical functions
"ceiling" and "floor" are wrong (inverted).

result is correct and as one would expect::
select ceiling(43.8); =>44
select floor(43.8);  =>43

documentation is misleading:
select ceiling(43.8); =>43
select floor(43.8); =>44

found in:
http://www.postgresql.org/docs/9.1/static/functions-math.html
http://www.postgresql.org/docs/7.4/static/functions-math.html

Cheers,
Patrick
