I'm trying to use the trig functions mentioned in the postgresql manual.
Namely the cosine function listed as
cos(float8) float8 cosine cos(0.4)
In both 6.5.3 and 7.0beta3 the function doesn't exist. I get. . .
obe-> \df cosine
result|function|arguments|description
------+--------+---------+-----------
(0 rows)
obe-> \df cos
result|function|arguments|description
------+--------+---------+-----------
(0 rows)
I didn't see any additional ./configure options to activate the math
functions, nor did I see any recent mention of this in the mail
archives. Am I missing something?
Also FWIW the manual lists the power function as pow which also doesn't
exist as pow but as power.
obe-> \df pow
result |function|arguments |description
-------+--------+----------------+--------------------------
numeric|power |numeric numeric |m raised to the power of n
(1 row)
Thanks,
James
