#7276: Fix PPC issues in totallyreal_rel.py
-----------------------------+----------------------------------------------
Reporter: kcrisman | Owner: davidloeffler

Component: number fields | Keywords: PPC, powerpc, lattice

Comment(by was):
The output on itanium (cleo) is exactly the same as on PPC above. I.e., I
get "last element is e-17".
So is there a bug somewhere in the algorithm that assumes some floating
point number is 0.0, but really it might just be epsilon sometimes, and
this is revealed on PPC and Itanium.
NOTE: Our PPC box is *big endian*. Our Itanium is *little endian*. So
this is not just an endianess issue.
