-/*							fac.c
- *
- *	Factorial function
- *
- *
- *
- * SYNOPSIS:
- *
- * double y, fac();
- * int i;
- *
- * y = fac( i );
- *
- *
- *
- * DESCRIPTION:
- *
- * Returns factorial of i  =  1 * 2 * 3 * ... * i.
- * fac(0) = 1.0.
- *
- * Due to machine arithmetic bounds the largest value of
- * i accepted is 33 in DEC arithmetic or 170 in IEEE
- * arithmetic.  Greater values, or negative ones,
- * produce an error message and return MAXNUM.
- *
- *
- *
- * ACCURACY:
- *
- * For i < 34 the values are simply tabulated, and have
- * full machine accuracy.  If i > 55, fac(i) = gamma(i+1);
- * see gamma.c.
- *
- *                      Relative error:
- * arithmetic   domain      peak
- *    IEEE      0, 170    1.4e-15
- *    DEC       0, 33      1.4e-17
