101     </p>
102 <p>
103       The function families currently implemented are the gamma, beta &amp; erf functions
104       along with the incomplete gamma and beta functions (four variants of each)
105       and all the possible inverses of these, plus digamma, various factorial functions,
106       Bessel functions, elliptic integrals, sinus cardinals (along with their hyperbolic
107       variants), inverse hyperbolic functions, Legrendre/Laguerre/Hermite polynomials
108       and various special power and logarithmic functions.
109     </p>
110 <p>
111       All the implementations are fully generic and support the use of arbitrary
112       "real-number" types, including <a href="../../../../../libs/multiprecision/doc/html/index.html" target="_top">Boost.Multiprecision</a>,
113       although they are optimised for use with types with known-about <a href="http://en.wikipedia.org/wiki/Significand" target="_top">significand
