Comment:

 Thanks.  I'm glad I asked, because before
 {{{
 sage: legendre_P(0,float(1))
 1
 sage: type(_)
 <type 'int'>
 }}}
 but now
 {{{
 sage: legendre_P(0,float(1))
 1
 sage: type(_)
 <type 'sage.rings.integer.Integer'>
 }}}

 Work:
  * So to my surprise, plotting these things works great.  It would be nice
 to add one or two examples.
  * I wouldn't ask for this on this ticket, but it probably should have one
 or two examples of the errors actually catching silly input.  I find it
 worthwhile to test those branches.
 Is that okay?
