2011-05-20 Brian Gough * hypot.c (gsl_hypot): handle case where x or y is infinite 2010-10-12 Brian Gough * pow_int.c (gsl_pow_uint): added function gsl_pow_uint(x,n) for unsigned n (larger range) (gsl_pow_int): handle case where n=MIN_INT correctly 2010-02-15 Brian Gough * infnan.c: use #error if gsl_isnan or gsl_finite cannot be defined 2009-08-21 Brian Gough * test.c (main): move x/=2 outside test of while loops because it is (possibly) not volatile. 2008-10-13 Brian Gough * log1p.c: use gsl_sys.h header file * infnan.c: use gsl_sys.h header file * hypot.c: use gsl_sys.h header file * fdiv.c: use gsl_sys.h header file * coerce.c: use gsl_sys.h header file 2008-10-08 Brian Gough * infnan.c (gsl_isinf): handle the case where isinf(-inf) returns +1 2008-07-03 Brian Gough * prec.c: compile inline functions from header here * pow_int.c: compile inline functions from header here * minmax.c: compile inline functions from header here 2008-03-18 Brian Gough * test.c (main): use volatile to avoid extended precision in loop * ldfrexp.c (gsl_ldexp): added a test for x==0 2007-11-04 Brian Gough * ldfrexp.c (gsl_ldexp): handle full range of double precision (gsl_frexp): handle full range of double precision 2007-07-30 Brian Gough * infnan.c (gsl_finite): use isfinite (c99) in preference to finite 2007-07-23 Brian Gough * log1p.c (gsl_log1p): added another volatile to prevent unwanted optimisation 2007-04-03 Brian Gough * infnan.c (gsl_isinf): now return -1 for -Inf instead of +1 * test.c (main): add test for -inf * infnan.c (gsl_finite): always use finite where available (gsl_isnan): always use isnan where available (gsl_isinf): always use isinf where available 2005-11-14 Brian Gough * test.c: added tests for constants 2005-04-05 Brian Gough * infnan.c: added #include ieeefp.h for Solaris 2004-12-22 Brian Gough * infnan.c (gsl_isinf): added missing return type of int 2003-09-02 Brian Gough * infnan.c (gsl_isinf): added fallback for missing isinf (IRIX) 2003-07-24 Brian Gough * invhyp.c: removed duplicate declarations * ldfrexp.c: removed duplicate declarations * expm1.c: removed duplicate declaration of gsl_expm1 2003-01-02 Brian Gough * 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 * ldfrexp.c: fix include to use instead of 2002-08-25 Brian Gough * fcmp.c (gsl_fcmp): approximate comparison of floating point numbers using Knuth's algorithm * ldfrexp.c (gsl_ldexp): portable replacement for ldexp() (gsl_frexp): portable replacement for frexp() Wed Jan 16 16:35:58 2002 Brian Gough * test.c (main): only test gsl_isnan, gsl_isinf, gsl_finite 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 * 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 * infnan.c: added gsl_isnan, gsl_isinf, gsl_isreal Sun Feb 25 11:54:21 2001 Brian Gough * invhyp.c: added gsl_acosh, gsl_asinh, gsl_atanh Mon Jan 29 10:53:06 2001 Brian Gough * hypot.c: removed the inline from gsl_hypot, since this is the static version of the function * test.c (main): added an underflow test for gsl_hypot Thu Nov 16 19:28:38 2000 Brian Gough * coerce.c: added functions for coercing values out of registers so they are correctly rounded Sun Oct 22 15:00:24 2000 Brian Gough * expm1.c (gsl_expm1): added gsl_expm1, a substitute for BSD's expm1 Mon Apr 3 16:58:53 2000 Brian Gough * params.c (main): added parentheses around negative output values Tue Mar 21 12:44:07 2000 Brian Gough * hypot.c: added a quick gsl_hypot function for sqrt(x^2+y^2) 1999-07-14 Mark Galassi * 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 * params.c: added program for printing ieee parameters
