@chapter Floating-Point Environment (@file{fenv.h})

This chapter groups the methods used to manipulate the floating-point
status flags. Floating-point operations modify the floating-point
status flags to indicate abnormal result information.

The implementation of these methods is architecture specific.

@menu
* feclearexcept::		Clear floating-point exception
* fegetenv::		Get current floating-point environment
* fegetexceptflag::	Get floating-point status flags
* fegetround::		Get current rounding direction
* feholdexcept::		Save current floating-point environment
* feraiseexcept::		Raise floating-point exception
* fesetenv::		Set current floating-point environment
* fesetexceptflag::	Set floating-point status flags
* fesetround::		Set current rounding direction
* fetestexcept::		Test floating-point exception flags
* feupdateenv::		Update current floating-point environment
