Re: Broken acos in PL/PGSQL?

Seems to work fine here

oss=> select acos(1);
acos
------
0
(1 row)

oss=> create function stest(integer) returns integer as '
oss'> declare
oss'> _num alias for $1;
oss'> begin
oss'> return acos(_num);
oss'> end;' language 'plpgsql';
CREATE
oss=> select stest(1);
stest
-------
0
(1 row)

Version information

oss=> select version();
version
-------------------------------------------------------------
PostgreSQL 7.2.1 on i686-pc-linux-gnu, compiled by GCC 2.96
(1 row)

What version are you running???
