-/*							asinhl.c
- *
- *	Inverse hyperbolic sine, long double precision
- *
- *
- *
- * SYNOPSIS:
- *
- * long double x, y, asinhl();
- *
- * y = asinhl( x );
- *
- *
- *
- * DESCRIPTION:
- *
- * Returns inverse hyperbolic sine of argument.
- *
- * If |x| < 0.5, the function is approximated by a rational
- * form  x + x**3 P(x)/Q(x).  Otherwise,
- *
- *     asinh(x) = log( x + sqrt(1 + x*x) ).
- *
- *
- *
- * ACCURACY:
- *
- *                      Relative error:
- * arithmetic   domain     # trials      peak         rms
- *    IEEE     -3,3         30000       1.7e-19     3.5e-20
