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