This is fine, but there was another one in functions/trig.py (this on a 32-bit Macintel 10.5):

sage: float(cot(1))
0.64209261593433065

but gave

0.64209261593433076

Hi Karl-Dieter,

attachment: trac_7609-pynac_numerical_noise.take2.patch adds a fix for the error you get as well. It is a good coincidence that you're testing on that box. :)

Thanks.

Okay, this seems good. I do still get the segfault in symbolic/expression.pyx but that is addressed elsewhere.
