[Bug-gsl] gsl_complex_div

[James Ward]

Dunno if this is a bug, but I was comparing the Complex Arithmetic
routines in Section 5.5 of Numerical Recipes, and gsl_complex_div()
uses simple complex division while 5.5.5 has a more sophisticated one
that avoids underflow/overflow.

gsl_complex_abs() should match 5.5.4 if hypot() is implemented
correctly on your machine, and gsl_complex_sqrt() matches 5.5.6 and
5.5.7.

Best wishes,

Jim Ward
