fesetenv
SYNOPSIS
#include <fenv.h>
int fesetenv(const fenv_t *<[envp]>);
Link with -lm.
DESCRIPTION
This method attempts to establish the floating-point environment
pointed to by <[envp]>. The argument <[envp]> must point to a
floating-point environment obtained via <<fegetenv>> or <<feholdexcept>>
or a floating-point environment macro such as <<FE_DFL_ENV>>.
It only sets the states of the flags as recorded in its argument, and
does not actually raise the associated floating-point exceptions.
RETURNS
If floating-point environment was successfully established, then
this method returns zero. Otherwise, a non-zero value is returned.
PORTABILITY
ANSI C requires <<fesetenv>>.
Not all Newlib targets have a working implementation. Refer to
the file <<sys/fenv.h>> to see the status for your target.
