Comment (by vdelecroix):
I am annoyed with the current implementation... it is written in the
generic `gcd` of `categories.fields` that
{{{
For fields of characteristic zero (i.e., containing the
integers as a sub-ring), evaluation in the integer ring is
attempted. This is for backwards compatibility.::
sage: gcd(6.0,8); gcd(6.0,8).parent()
2
Integer Ring
}}}
This is completely crazy! And moreover different from what is in gcd!!
