There may be another reason to use a single summation function. The 
summation functions does need (a copy of) the is_error() function from 
the math module.
The cmath module has a similar function called math_error() which 
slightly different from is_error().
It would be better, more consistent if both modules used the same 
function, say is_error() moved** to file Object/floatobject.c
Then, the math and cmath module can use ist_error() instead of each 
their own. Also, the summation function can use it and function 
float_pow() in floatobject.c could.
