- *      Gamma function
- *
- *
- * SYNOPSIS:
- *
- * long double x, y, tgammal();
- *
- * y = tgammal( x );
- *
- *
- * DESCRIPTION:
- *
- * Returns gamma function of the argument.  The result is
- * correctly signed.
- *
- * Arguments |x| <= 13 are reduced by recurrence and the function
- * approximated by a rational function of degree 7/8 in the
- * interval (2,3).  Large arguments are handled by Stirling's
- * formula. Large negative arguments are made positive using
- * a reflection formula.
- *
- *
- * ACCURACY:
- *
- *                      Relative error:
- * arithmetic   domain     # trials      peak         rms
- *    IEEE     -40,+40      10000       3.6e-19     7.9e-20
- *    IEEE    -1755,+1755   10000       4.8e-18     6.5e-19
- *
- * Accuracy for large arguments is dominated by error in powl().
