[Help-gsl] gsl_sum (potential division by zero?)

[Michel Van den Bergh]

Hi,

I was looking at the code for gsl_sum. I have not completely understood
it yet,
but I noticed that whereas levin_utrunc.c explicitly tests for terms
that are zero,
this is not the case for levin_u.c. As one divides by such terms, it
seems that
one may potentially divide by zero this way. Am I wrong?

The documentation does not seem to mention that terms should be
different from zero.

Regards,
Michel
