Implementations on Foreign Types

impl Li2<f64> for f64

fn li2(&self) -> f64

Returns the real dilogarithm of a real number of type f64.

This function has been translated from the ROOT package. Original implementation by K.S. Kölbig into CERNLIB DILOG function C332, translated to C++ by R.Brun.

Implemented as a truncated series expansion in terms of Chebyshev polynomials, see [Yudell L. Luke: Mathematical functions and their approximations, Academic Press Inc., New York 1975, p.67].

Example:

use polylog::Li2;

let z = 1.0;
println!("Li2({}) = {}", z, z.li2());

impl Li2<Complex<f64>> for Complex<f64>

fn li2(&self) -> Complex<f64>

Returns the dilogarithm of a complex number of type Complex<f64>.

This function has been translated from the SPheno package.

Example:

extern crate num;
extern crate polylog;
use num::complex::Complex;
use polylog::Li2;

fn main() {
    let z = Complex::new(1.0, 1.0);
    println!("Li2({}) = {}", z, z.li2());
}
