Nature of problem:
The Fermi-Dirac function appears in a wide range of physical applications. The package contains a function routine to calculate Fsigma(alpha) for sigma greater than 0 and all real alpha.

Solution method:
The method of solution is based on the series of expansions of Rhodes, Nordheim, McDougall and Stoner and the authors.

Restrictions:
The relative accuracy parameter EPS should not be set below 10**-5. The restriction is imposed in order to avoid a possible underflow condition. The user can improve the accuracy, depending on the computing system employed.

Running time:
Running times are below 1 s.
