Positive review. By the way,
{{{
sage: a =
RIF(3.9999999999999999999999999999999999,5.000000000000000000000000000000000)
sage: b =
RIF(4.000000000000000000000000000000000,4.9999999999999999999999999999999999)
sage: a.is_int()
(False, None)
sage: b.is_int()
(False, None)
}}}
though I don't know if that's a bug (except in user input), since
{{{
sage: a.str(style='brackets')
'[3.9999999999999995 .. 5.0000000000000000]'
sage: b.str(style='brackets')
'[4.0000000000000000 .. 5.0000000000000000]'
}}}
but anyway wanted to point it out in case this is considered something
that should be documented in is_int(), not just in RIF().
