Comment(by mhansen):
There are a couple of issues for this. The first is converting to Maxima
which is currently
{{{
sage: a._maxima_init_()
'8.9875517873681755065917968750000000000000000000000000000000000e9'
}}}
should be done with something like:
calculus.symbolic_expression_from_string
{{{
sage: a._maxima_init_()
'8.987551787368175506591796875b9,fpprec:200'
}}}
Then, there is an issue going from Maxima to Sage. In
{{{sage.calculus.calculus.calculus.symbolic_expression_from_string}}},
{{{sage.rings.real_mpfr.create_RealNumber}}}, but does not pass it any
precision. This should try and detect the precision of the bigfloat.
