2003-01-02  Brian Gough  <brian.gough@network-theory.co.uk>

	* infnan.c (gsl_isnan): fall back to isnan,isinf,finite/isfinite
	if available and IEEE comparisons do not work

Wed Dec 11 17:29:24 2002  Brian Gough  <brian.gough@network-theory.co.uk>

 	functions if they have been compiled in.

	* infnan.c (gsl_isnan): #ifdef out the gsl_isnan, gsl_isinf and
 	gsl_finite functions if IEEE comparisons for nans and infs are not
 	supported (HAVE_IEEE_COMPARISONS).

Tue Aug 21 22:54:08 2001  Brian Gough  <bjg@network-theory.co.uk>

	* test.c (main): use inf/inf to generate a nan, because MSVC
 	optimizes inf-inf to zero

Sun May  6 14:28:57 2001  Brian Gough  <bjg@network-theory.co.uk>

	* infnan.c: added gsl_isnan, gsl_isinf, gsl_isreal

Sun Feb 25 11:54:21 2001  Brian Gough  <bjg@network-theory.co.uk>

	* invhyp.c: added gsl_acosh, gsl_asinh, gsl_atanh

Mon Jan 29 10:53:06 2001  Brian Gough  <bjg@network-theory.co.uk>

 	static version of the function

Thu Nov 16 19:28:38 2000  Brian Gough  <bjg@network-theory.co.uk>

1999-07-14  Mark Galassi  <rosalia@cygnus.com>

	* prec.c (GSL_MODE_PREC): surrounded this with function with an
	#ifndef, since it might already be defined as a macro.  In truth,
	this function might be completely unnecessary, since the logic in
	../gsl_mode.h seems to cover all cases.

Fri Nov 20 17:41:35 1998  Brian Gough  <bjg@vvv.lanl.gov>

	* params.c: added program for printing ieee parameters
