FEGETENV(P)		   POSIX Programmer's Manual		   FEGETENV(P)

NAME
       fegetenv, fesetenv - get and set current floating-point environment

SYNOPSIS
       #include <fenv.h>

       int fegetenv(fenv_t *envp);
       int fesetenv(const fenv_t *envp);

DESCRIPTION
       The  fegetenv()	function  shall attempt to store the current floating-
       point environment in the object pointed to by envp.

       The fesetenv() function shall attempt to establish  the	floating-point
       environment  represented by the object pointed to by envp. The argument
       envp shall point to an object set by a call to fegetenv() or  feholdex‐
       cept(),	or  equal  a  floating-point environment macro. The fesetenv()
       function does not raise floating-point exceptions,  but	only  installs
       the  state  of  the floating-point status flags represented through its
       argument.

RETURN VALUE
       If the representation was successfully stored, fegetenv() shall	return
       zero.  Otherwise, it shall return a non-zero value.  If the environment
       was successfully established, fesetenv() shall return zero.  Otherwise,
       it shall return a non-zero value.
