Trac #8185 "numerical noise + crash on sage/calculus/functional.py"
This fixes a numerical noise issue seen on two SPARC machines.
A crash which appeared one machine (hence title), is unrelated to this.
Previously, there was:
Expected:
0.85914091422952255
Got:
0.85914091422952277
This fixes that problem.
