DESCRIPTION
This is an interface to the Special Function package present in the GNU Scientific Library.
SYNOPSIS FUNCTIONS
gsl_sf_clausen
Signature: (double x(); double [o]y(); double [o]e())
Clausen Integral. Cl_2(x) := Integrate[-Log[2 Sin[t/2]], {t,0,x}]
gsl_sf_clausen does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input
piddles.

/* Real part of DiLogarithm(x), for real argument. In Lewins notation, this is Li_2(x). Li_2(x) = - Re[ Integrate[ Log[1-s] / s, {s, 0, x}]
]
gsl_sf_dilog does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input
piddles.
