fermi_dirac_integ_direct
¶ Compute the Fermi-Dirac integral by directly integrating with a higher precision type.
This class performs direct computation of the Fermi-Dirac integral
\[ F_{a}(\mu) = \int_0^{\infty} \frac{x^a}{1+e^{x-\mu}} \, . \]Note that the GSL definition of the Fermi-Dirac integral includes an additional factor of \( 1/\Gamma(a+1) \) which is not included here.
