[GiNaC-list] converting expressions to double

[Jens Vollinga]

Hi,

could you run your code with an added extra line like the following:

...
	ex = ex.subs(lst(x == _x, y == _y, z == _z, u == _u));
	ex = ex.evalf();
	std::cout << tree << ex << std::endl;  /* NEW NEW NEW */
	numeric tmp = ex_to<numeric>(ex);
...

and report about the result? That would help pin down the problem.

Regards,
Jens
