Comment:
Some copy/paste accidents (could probably be corrected on the follow-ups):
{{{
+ def previous_prime(self, proof=None):
+ r"""
+ Returns the previous prime before self.
+
+ This method calls the PARI ``precprime`` function.
+
+ INPUT:
+
+ - ``proof`` - if ``True`` ensure that the returned value is the
next
+ prime power and if set to ``False`` uses probabilistic methods
+ (i.e. the result is not guaranteed). By default it uses global
+ configuration variables to determine which alternative to use
(see
+ :mod:`proof.arithmetic` or :mod:`sage.structure.proof`).
