One can calculate factorials of RIF-Elements with
{{{
sage: factorial(RIF(2.3,5.7))
1.?e3
}}}
but calling it by
{{{
sage: (RIF(2.3,5.7)).factorial()
Traceback (click to the left of this block for traceback)
...
AttributeError: 'sage.rings.real_mpfi.RealIntervalFieldElement' object
has no attribute 'factorial'
}}}
does not work. This is in contrast to {{{.log()}}}, {{{.sqrt()}}}, etc.,
where it works.
