Comment (by dimpase):
Replying to [comment:27 vbraun]:
> Well I don't have Mathematica, you'll have to look at
`sage.misc.functional.numerical_approx` yourself. Whats
`mathematica('Pi').prec()`?
it is a symbolic Mathematica expression `prec[Pi]`. It cannot be evaluated
to anything.
Evaluating `mathematica('Pi').n()`, on Mathematica side I see the
following:
{{{
In[1]:= sage0=Pi;
In[2]:= sage1=0;
In[3]:= sage2=gen[sage1];
In[4]:= sage1=prec[sage0];
In[5]:= sage3=1;
In[6]:= sage3=53;
In[7]:= sage1 < sage3
Out[7]= prec[Pi] < 53
In[8]:= sage1 > sage3
Out[8]= prec[Pi] > 53
In[9]:= sage1 == sage3
Out[9]= prec[Pi] == 53
In[10]:= sage1
Out[10]= prec[Pi]
}}}
(in comment 22 I posted the corresponding log for `.n(10)` (I made a typo,
wrote that it is `.n()`, now corrected there).
