Comment (by mmezzarobba):
Also, do you know if this branch is really used anywhere?
{{{
# try coercing to real
try:
ra = self._parent._lower_field()(x)
rb = self._parent._upper_field()(x)
}}}
I'm far from convinced that conversions of sage objects to real fields
with directed rounding really return upper/lower bounds...
