lucas2 #81

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
The doc-string for lucas2  states that is should return the n-1 th and n th 
Lucas numbers, but it appears to return something else. E.g.

>>> from gmpy2 import lucas, lucas2

>>> lucas(15)
mpz(1364)

>>> lucas(14)
mpz(843)

>>> lucas2(15)  # we expect (mpz(1364), mpz(843))
(mpz(610), mpz(377))

These aren't even Lucas numbers[1]. Is this a bug or am I just misinterpreting 
the docstring?

It's a bug. :-( I called fib2 instead of luc2...

I'll release 2.03 with the fix in a couple of days (after 3.4b1 is released).

Thanks for the report.
