+@cindex signal
+
+Due to the restrictions in the size of the floating-point number
+representation or the limitation of the input range of certain functions
+some of the mathematical operations and functions have to signal
+exceptional situations.  The @w{IEEE 754} standard specifies which
+exceptions have to be supported and how they can be handled.
+
+@w{IEEE 754} specifies two actions for floating-point exception: taking
+a trap or continuing without doing so.  If the trap is taken a
+(possibly) user defined trap handler is called and this function can
+correct the argument or react somehow else on the call.  If the trap
+handler returns, its return value is taken as the result of the
+operation.
+
+If no trap handler is called each of the known exceptions has a default
+action.  This consists of setting a corresponding bit in the
+floating-point status word to indicate which kind of exception was
+raised and to return a default value, which depends on the exception
+(see the table below).

+@noindent
+The exceptions defined in @w{IEEE 754} are:

+@w{ISO C 9X} introduces a set of function which can be used to control

+@end menu
+
+@node Status bit operations
+@subsection Controlling the FPU status word
+
+To control the five types of exceptions defined in @w{IEEE 754} some
+functions are defined which abstract the interface to the FPU.  The
+actual implementation can be very different, depending on the underlying
+hardware or software.
+
+To address the single exception the @file{fenv.h} headers defines a
+number macros:
+
+@vtable @code
+@comment fenv.h
+@comment ISO
+@item FE_INEXACT
+Represent the inexact exception iff the FPU supports this exception.
+@comment fenv.h
+@comment ISO
+@item FE_DIVBYZERO
+Represent the divide by zero exception iff the FPU supports this exception.
+@comment fenv.h
+@comment ISO
+@item FE_UNDERFLOW
+Represent the underflow exception iff the FPU supports this exception.
+@comment fenv.h
+@comment ISO
+@item FE_OVERFLOW
+Represent the overflow exception iff the FPU supports this exception.
+@comment fenv.h
+@comment ISO
+@item FE_INVALID
+Represent the invalid exception iff the FPU supports this exception.
+@end vtable
+
+The macro @code{FE_ALL_EXCEPT} is the bitwise OR of all exception macros
+which are supported by the FP implementation.
+
+Each of the supported exception flag can either be set or unset.  The
+@w{ISO C 9X} standard defines functions to set, unset and test the
+status of the flags.
+
+@comment fenv.h
+@comment ISO
+@deftypefun void feclearexcept (int @var{excepts})
+This functions clears all of the supported exception flags denoted by
+@var{excepts} in the status word.
+@end deftypefun
+
+To safe the current status of the flags in the status word @file{fenv.h}
+defines the type @code{fexcept_t} which can hold all the information.
+The following function can be used to retrieve the current setting.
+
+@comment fenv.h
+@comment ISO
+@deftypefun void fegetexceptflag (fexcept_t *@var{flagp}, int @var{excepts})
+Store in the variable pointed to by @var{flagp} an
+implementation-defined value representing the current setting of the
+exception flags indicated by the parameter @var{excepts}.
+@end deftypefun
+
+@noindent
+To restore the previously saved values one can use this functions:
+
+@comment fenv.h
+@comment ISO
+@deftypefun void fesetexceptflag (const fexcept_t *@var{flagp}, int @var{excepts})
+Restore from the variable pointed to by @var{flagp} the setting of the
+flags for the exceptions denoted by the value of the parameter
+@var{excepts}.
+@end deftypefun
+
+The last function allows to query the current status of the flags.  The
+flags can be set either explicitely (using @code{fesetexceptflag} or
+@code{feclearexcept}) or by a floating-point operation which happened
+before.  Since the flags are accumulative, the flags must be explicitely
+reset using @code{feclearexcept} if one wants to test for a certain
+exceptions raised by a specific piece of code.
+
+@comment fenv.h
+@comment ISO
+@deftypefun int fetestexcept (int @var{excepts})
+Test whether a subset of the flags indicated by the parameter
+@var{except} is currently set.  If yes, a nonzero value is returned
+which specifies which exceptions are set.  Otherwise the result is zero.
+@end deftypefun
+
+@noindent
+Code which uses the @code{fetestexcept} function could look like this:
+
+@smallexample
+@{
+  double f;
+  int raised;
+  feclearexcept (FE_ALL_EXCEPT);
+  f = compute ();
+  raised = fetestexcept (FE_OVERFLOW | FE_INVALID);
+  if (raised & FE_OVERFLOW) @{ /* ... */ @}
+  if (raised & FE_INVALID) @{ /* ... */ @}
+  /* ... */
+@}
+@end smallexample
+
+Please note that the return value of @code{fetestexcept} is @code{int}
+but this does not mean that the @code{fexcept_t} type is generally
+representable as an integer.  These are completely independent types.
+
+
+@node FPU environment
+@subsection Controlling the Floating-Point environment
+
+It is sometimes necessary so save the complete status of the
+floating-point unit for a certain time to perform some completely
+different actions.  Beside the status of the exception flags, the
+control word for the exceptions and the rounding mode can be safed.
+
+The file @file{fenv.h} defines the type @code{fenv_t}.  The layout of a
+variable of this type is implementation defined but the variable is able
+to contain the complete status informations.  To fill a variable of this
+type one can use this function:
+
+@comment fenv.h
+@comment ISO
+@deftypefun void fegetenv (fenv_t *@var{envp})
+Store the current floating-point environment in the object pointed to by
+@var{envp}.
+@end deftypefun
+
+@noindent
+Another possibility which is useful is several situations is
+
+@comment fenv.h
+@comment ISO
+@deftypefun int feholdexcept (fenv_t *@var{envp})
+Store the current floating-point environment in the object pointed to by
+@var{envp}.  Afterwards, all exception flags are cleared and if
+available a mode is installed which continues on all exception and does
+not cause a trap to occur.  In ths case a nonzero value is returned.
+
+If the floating-point implementation does not support such a non-stop
+mode, the return value is zero.
+@end deftypefun
+
+The functions which allow a state of the floating-point unit to be
+restored can take two kinds of arguments:
+
+@itemize @bullet
+@item
+Pointed to objects which previously were initialized by a call to
+@code{fegetenv} or @code{feholdexcept}.
+@item
+@vindex FE_DFL_ENV
+The special macro @code{FE_DFL_ENV} which represents the floating-point
+environment as it was available at program start.
+@item
+Implementation defined macros with names starting with @code{FE_}.
+
+@vindex FE_NOMASK_ENV
+If possible, the GNU C Library defines a macro @code{FE_NOMASK_ENV}
+which represents an environment where no exception is masked and so each
+raised exception causes a trap to occur.  Whether this macro is available can easily be tested using @code{#ifdef}.
+
+Some platforms might define further predefined environments.
+@end itemize
+
+@noindent
+To set any of the environments there are two functions defined.
+
+@deftypefun void fesetenv (const fenv_t *@var{envp})
+Establish the floating-point environment described in the object pointed
+to by @var{envp}.  Even if one or more exceptions flags in the restored
+environment are set no exception is raised.
+@end deftypefun
+
+In some situations the previous status of the exception flags must not
+simply be discarded and so this function is useful:
+
+@deftypefun void feupdateenv (const fenv_t *@var{envp})
+The current status of the floating-point unit is preserved in some
+automatic storage before the environment described by the object pointed
+to by @var{envp} is installed.  Once this is finished all exceptions set
+in the original environment which is saved in the automatic storage, is
+raised.
+@end deftypefun
+
+This function can be used to execute a part of the program with an
+environment which masks all exceptions and before switching back remove
+unwanted exception and raise the remaining exceptions.
+
+
+@node Rounding Modes
+@subsection Rounding modes of the Floating-Point Unit
+
+@w{IEEE 754} defines four different rounding modes.  If the rounding
+mode is supported by the floating-point implementation the corresponding
+of the following macros is defined:
+
+@vtable @code
+@comment fenv.h
+@comment ISO
+@item FE_TONEAREST
+Round to nearest.  This is the default mode and should always be used
+except when a different mode is explicitely required.  Only rounding to
+nearest guarantees numeric stability of the computations.
+
+@comment fenv.h
+@comment ISO
+@item FE_UPWARD

+@math{-oo}.
+@end ifclear
+
+@comment fenv.h
+@comment ISO
+@item FE_TOWARDZERO
+Round toward zero.
+@end vtable
+
+At any time one of the four rounding modes above is selected.  To get
+information about the currently selected mode one can use this function:
+
+@comment fenv.h
+@comment ISO
+@deftypefun int fegetround (void)
+Return the currently selected rounding mode, represented by one of the
+values of the defined rouding mode macros.
+@end deftypefun
+
+@noindent
+To set a specific rounding mode the next function can be used.
+
+@comment fenv.h
+@comment ISO
+@deftypefun int fesetround (int @var{round})
+Change the currently selected rounding mode to the mode described by the
+parameter @var{round}.  If @var{round} does not correspond to one of the
+supported rounding modes nothing is changed.
+
+The function return a nonzero value iff the requested rounding mode can
+be established.  Otherwise zero is returned.
+@end deftypefun
+
+Changing the rounding mode can be necessary for various reasons.  But
+changing the mode only to round a given number normally is no good idea.
+The standard defines a set of functions which can be used to round an
+argument according to some rules and for all of the rounding modes there
+is a corresponding function.
+
+If a large set of number has to be rounded it might be good to change
+the rounding mode and do not use the function the library provides.  So
+the perhaps necessary switching of the rounding mode in the library
+function can be avoided.  But since not all rounding modes are
+guaranteed to exist on any platform this possible implementation cannot
+be portably used.  A default method has to be implemented as well.

+The header @file{math.h} defines a series of mathematical constants if

+@end vtable
+
+ALl values are defined as @code{long double} values unless the compiler
+does not support this type or @code{__STDC__} is not defined (both is
+unlikey).  Historically the numbers were @code{double} values and some
+old code still relies on this so you might want to add explizit casts if
+the extra precision of the @code{long double} value is not needed.  One
+critical case are functions with a variable number of arguments, such as
+@code{printf}.
+
+@vindex PI
+@emph{Note:} Some programs use a constant named @code{PI} which has the
+same value as @code{M_PI}.  This probably derives from Stroustroup's
+book about his C++ programming language where this value is used in
+examples (and perhaps some AT&T headers contain this value).  But due to
+possible name space problems (@code{PI} is a quite frequently used name)
+this value is not added to @file{math.h}.  Every program should use
+@code{M_PI} instead or add on the the compiler command line
+@code{-DPI=M_PI}.

+starts.  In the first implementations the type of these variables was
