John,
Could you test the latest version (ver. 13) of my fpclassify library? It is available in the vault in the directory Math-Numerics.
The library is based on a helper class fp_traits<T> that contains information about the binary representation of T. Here T = float, double or long double. The generic version of fp_traits<T> is initialized at run time, and is hence safe but also slow. Then there are fast specializations of fp_traits<T> for different floating point types T, operating systems and processors.
The library does not use the limits and boost/endian.hpp headers.
The library has been tested on the following platforms:
Win / MSVC 7.1 / x86 Mac / GCC 3.3, GCC 4.0 / ppc Linux / GCC 3.3 / x86, x64, ia64, ppc, hppa, mips, m68k
Let's see if you can break it!
OK :-) HP testdrive is down at present, so I can only test on Win32: Intel 8 and 9 pass, but Intel 7 fails: $ icl -GX -I.. -I../../release/boost -Ox *.cpp Intel(R) C++ Compiler for 32-bit applications, Version 7.1 Build 20040309Z Copyright (C) 1985-2004 Intel Corporation.
