Hi All,
I'm new to sage.  I'm very impressed and a bit overwhelmed at the
capabilities in sage.  I noticed a discrepancy today that I can't
reconcile in the response of bessel functions.  I get different values
depending on how I invoke it.  For example, the bessel J functions
don't have zeros!  I have sample output below.  Can anyone tell me what
I'm doing wrong or if there is a known bug or patch?

thanks

pari(2).besselj(3)
#
# 0.48609126058589108
#
#

bessel_J(2,3)
#
# 0.12894324947440206
#
#

bessel_J(2,3,'maxima')
#
# 0.48609126058589119
#
#

bessel_J(2,3,'pari',80)
#
# 0.12894324947440205109879323
#
#

(0.486...) is the right value.
So what is Sage calculating with the default interface and the 'pari'
argument?

Oh, I'm using pari-2.3.1 on linux RH9.
btw, the web notebook interface is the coolest thing I've seen in a
long time.
