Comment (by dimpase):
OK, at least I understand the reason for `N()` to output seemingly random
length things.
Namely, the interface works with M-ca's `InputForm`; e.g. when
`mathematica('Pi').N(10)`
is computed, intermediate data is stored in `InputForm`, and it is on my
system
{{{
3.14159265358979323846264338327950419993`10.
}}}
Then `get()` is called, and it does (line 528 of `mathematica.py`)
{{{
return self.eval('InputForm[%s, NumberMarks->False]'%var, strip=True)
}}}
stripping `10` after the tick away! Oops...
One workaround would be to provide an implementation of `N()` avoiding
`get` all together.
