Correct. fenv.h is available from 11.00 onward. The following calls
are defined:
extern void feclearexcept(int);
extern void fegetexceptflag(fexcept_t *, int);
extern void feraiseexcept(int);
extern void fesetexceptflag(const fexcept_t *, int);
extern int fetestexcept(int);
extern int fegetround(void);
extern int fesetround(int);
extern void fegetenv(fenv_t *);
extern int feholdexcept(fenv_t *);
extern void fesetenv(const fenv_t *);
extern void feupdateenv(const fenv_t *);
extern int fegetflushtozero(void);
extern void fesetflushtozero(int);
extern int fegettrapenable(void);
extern void fesettrapenable(int);
In addition, ia64 has:
extern int fegetprec(void);
extern int fesetprec(int);
Documentation is getting harder to get online. The following link is
for ia64 but should be mostly
relevant :
http://h21007.www2.hp.com/portal/site/dspp/menuitem.863c3e4cbcdc3f3515b49c108973a801/?ciid=0008a22194f02110a22194f02110275d6e10RCRD
I have an older pdf version that is parisc specific.
It seems HP no longer has man pages online, so third-party links are
all that's available:

Thanks,
