- *	Hyperbolic cosine
- *
- *
- *
- * SYNOPSIS:
- *
- * float x, y, coshf();
- *
- * y = coshf( x );
- *
- *
- *
- * DESCRIPTION:
- *
- * Returns hyperbolic cosine of argument in the range MINLOGF to
- * MAXLOGF.
- *
- * cosh(x)  =  ( exp(x) + exp(-x) )/2.
- *
- *
- *
- * ACCURACY:
- *
- *                      Relative error:
- * arithmetic   domain     # trials      peak         rms
- *    IEEE     +-MAXLOGF    100000      1.2e-7      2.8e-8
- *
- *
- * ERROR MESSAGES:
- *
- *   message         condition      value returned
- * coshf overflow  |x| > MAXLOGF       MAXNUMF
