@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
