I view this as a problem - was trying to construct the Weierstrass
function for my students
http://sagecell.sagemath.org/?q=mufyfu
and it wouldn't plot right until I changed %2 to %2., but now I get
this. Or is there some mathematical reason to be inconsistent here?
It's not a bug, it works as documented...
Why do you say it is working as documented? It looks like a bug to me.
FYI, you can work with RDF - the behavior is same as the integer case.
sage: aa = RDF(5.0)
sage: aa % 3

luckily, I knew where the
documentation would hide for this! Others might not.
def __mod__(left, right):
"""
Return the value of ``left - n*right``, rounded according to the
rounding mode of the parent, where ``n`` is the integer quotient of
``x`` divided by ``y``. The integer ``n`` is rounded toward the
nearest integer (ties rounded to even).
