Hi!
I'm trying to port a C program written originally in
Linux to the Microsoft Windows plataform.
I've realized that math.h under cygwin doesn't
define the macro HUGE, that is defined in
the math.h under linux:
/* Declarations for math functions.
Copyright (C) 1991-1993,1995-1999,2001,2002 Free Software Foundation, Inc.
This file is part of the GNU C Library.
*/
/* SVID mode specifies returning this large value instead of infinity. */
# define HUGE 3.40282347e+38F
I thought math.h should be quite portable ...
HUGE is not portable. It's not defined in the standard, see
http://www.opengroup.org/onlinepubs/009695399/basedefs/math.h.html
Use HUGE_VAL instead.
However, other definitions are missing in math.h, like HUGE_VALF,
HUGE_VALL, INFINITY and NAN.
I'll take a look at adding these unless you want to. HUGE_VALL is the
only one that is difficult.
Since math.h is part of newlib, I've redirect this posting to the
newlib mailing list.
