Description
Popped up in Sage 7.4.beta2 (or probably some earlier beta):
---------------------------------------------------------------------- sage -t --long src/sage/libs/gap/assigned_names.py # 1 doctest failed sage -t --long src/sage/symbolic/function.pyx # 1 doctest failed ---------------------------------------------------------------------- The first is the usual failure, the second is new, and I don't know where it originates from (as the doctest itself hasn't changed): ********************************************************************** File "src/sage/symbolic/function.pyx", line 667, in sage.symbolic.function.Function._fast_float_ Failed example: ff(1.5) Expected: 0.9661051464753108 Got: 0.9661051464753109 **********************************************************************
(Native build on Haswell.)
