-/*							log1pl.c
- *
- *      Relative error logarithm
- *	Natural logarithm of 1+x, 128-bit long double precision
- *
- *
- *
- * SYNOPSIS:
- *
- * long double x, y, log1pl();
- *
- * y = log1pl( x );
- *
- *
- *
- * DESCRIPTION:
- *
- * Returns the base e (2.718...) logarithm of 1+x.
- *
- * The argument 1+x is separated into its exponent and fractional
- * parts.  If the exponent is between -1 and +1, the logarithm
- * of the fraction is approximated by
- *
- *     log(1+x) = x - 0.5 x^2 + x^3 P(x)/Q(x).
- *
- * Otherwise, setting  z = 2(w-1)/(w+1),
- *
- *     log(w) = z + z^3 P(z)/Q(z).
- *
- *
- *
- * ACCURACY:
- *
- *                      Relative error:
- * arithmetic   domain     # trials      peak         rms
- *    IEEE      -1, 8       100000      1.9e-34     4.3e-35
