Broken acos in PL/PGSQL?

I just ran into a show stopper exception on one of my systems. It seems the 
acos() function in PL/PGSQL throws an exception if it's called with a 1. All 
other acos() implementations I've ever used return a zero. I did some poking 
around and every acos() reference I could find for other software returns a 
zero. Is Postgres' implementation intentional or an oversight? In the context 
of my application, zero is the correct value to return in this case.
