I was just looking at the numeric limits stuff, and noticed that
numeric_limits<>::infinity(), quiet_NaN() and signaling_NaN() are all set to
return zero for all the floating point types.
On Solaris there is a library (sunmath) that provides functions to obtain these
values, which can then be used in gen_num_limits.cc to provide them without
requiring this library.
Are there such functions available on other platforms (e.g. as part of glibc)?
Would you like the code I've written for gen_num_limits.cc which uses these on
Solaris?
