SYNOPSIS

FUNCTIONS

14   gsl_sf_dilog
15         Signature: (double x(); double [o]y(); double [o]e())
16
17       /* Real part of DiLogarithm(x), for real argument. In Lewins notation,
18       this is Li_2(x). Li_2(x) = - Re[ Integrate[ Log[1-s] / s, {s, 0, x}] ]
19
20       gsl_sf_dilog does not process bad values.  It will set the bad-value
21       flag of all output piddles if the flag is set for any of the input
22       piddles.
23
24   gsl_sf_complex_dilog
25         Signature: (double r(); double t(); double [o]re(); double [o]im(); double [o]ere(); double [o]eim())
26
27       DiLogarithm(z), for complex argument z = r Exp[i theta].
28
29       gsl_sf_complex_dilog does not process bad values.  It will set the bad-
30       value flag of all output piddles if the flag is set for any of the
31       input piddles.
