- *      Exponential function, minus 1
- *      Long double precision
- *
- *
- * SYNOPSIS:
- *
- * long double x, y, expm1l();
- *
- * y = expm1l( x );
- *
- *
- * DESCRIPTION:
- *
- * Returns e (2.71828...) raised to the x power, minus 1.
- *
- * Range reduction is accomplished by separating the argument
- * into an integer k and fraction f such that
- *
- *     x    k  f
- *    e  = 2  e.
- *
- * An expansion x + .5 x^2 + x^3 R(x) approximates exp(f) - 1
- * in the basic range [-0.5 ln 2, 0.5 ln 2].
- *
- *
- * ACCURACY:
- *
- *                      Relative error:
- * arithmetic   domain     # trials      peak         rms
- *    IEEE    -45,+maxarg   200,000     1.2e-19     2.5e-20
