18.  def feclearexcept(excepts: CInt): CInt

    Attempts to clear the floating-point exceptions that are listed in the bitmask argument excepts, which is a bitwise OR of the floating-point exception macros.

    Attempts to clear the floating-point exceptions that are listed in the bitmask argument excepts, which is a bitwise OR of the floating-point exception macros.

    excepts

    bitmask listing the exception flags to clear

    returns

    ​0​ if all indicated exceptions were successfully cleared or if excepts is zero. A non-zero value on error.

19.  def fegetenv(envp: Ptr[fenv_t]): CInt

    1) Attempts to store the status of the floating-point environment in the object pointed to by envp.

    1) Attempts to store the status of the floating-point environment in the object pointed to by envp.

    envp

    pointer to the object of type fenv_t which holds the status of the floating-point environment

    returns

    ​0​ on success, non-zero otherwise.

20.  def fegetexceptflag(flagp: Ptr[fexcept_t], excepts: CInt): CInt

    Attempts to obtain the full contents of the floating-point exception flags that are listed in the bitmask argument excepts, which is a bitwise OR of the floating-point exception macros.

    Attempts to obtain the full contents of the floating-point exception flags that are listed in the bitmask argument excepts, which is a bitwise OR of the floating-point exception macros.

    flagp

    pointer to an fexcept_t object where the flags will be stored or read from

    excepts

    bitmask listing the exception flags to get/set

    returns

    ​0​ on success, non-zero otherwise.

21.  def fegetround(): CInt

    Returns the value of the floating-point rounding macro that corresponds to the current rounding direction.

    Returns the value of the floating-point rounding macro that corresponds to the current rounding direction.

    returns

    the floating-point rounding macro describing the current rounding direction or a negative value if the direction cannot be determined.

22.  def feholdexcept(envp: Ptr[fenv_t]): CInt

    First, saves the current floating-point environment to the object pointed to by envp (similar to fegetenv), then clears all floating-point status flags, and then installs the non-stop mode: future floating-point exceptions will not interrupt execution (will not trap), until the floating-point environment is restored by feupdateenv or fesetenv.

    First, saves the current floating-point environment to the object pointed to by envp (similar to fegetenv), then clears all floating-point status flags, and then installs the non-stop mode: future floating-point exceptions will not interrupt execution (will not trap), until the floating-point environment is restored by feupdateenv or fesetenv.

    This function may be used in the beginning of a subroutine that must hide the floating-point exceptions it may raise from the caller. If only some exceptions must be suppressed, while others must be reported, the non-stop mode is usually ended with a call to feupdateenv after clearing the unwanted exceptions.

    envp

    pointer to the object of type fenv_t where the floating-point environment will be stored

    returns

    ​0​ on success, non-zero otherwise.

23.  def feraiseexcept(excepts: CInt): CInt

    Attempts to raise all floating-point exceptions listed in excepts (a bitwise OR of the floating-point exception macros).

    Attempts to raise all floating-point exceptions listed in excepts (a bitwise OR of the floating-point exception macros). If one of the exceptions is FE_OVERFLOW or FE_UNDERFLOW, this function may additionally raise FE_INEXACT. The order in which the exceptions are raised is unspecified, except that FE_OVERFLOW and FE_UNDERFLOW are always raised before FE_INEXACT.

    excepts

    bitmask listing the exception flags to raise

    returns

    ​0​ if all listed exceptions were raised, non-zero value otherwise.

24.  def fesetenv(envp: Ptr[fenv_t]): CInt

    2) Attempts to establish the floating-point environment from the object pointed to by envp.

    2) Attempts to establish the floating-point environment from the object pointed to by envp. The value of that object must be previously obtained by a call to feholdexcept or fegetenv or be a floating-point macro constant. If any of the floating-point status flags are set in envp, they become set in the environment (and are then testable with fetestexcept), but the corresponding floating-point exceptions are not raised (execution continues uninterrupted)

    envp

    pointer to the object of type fenv_t which holds the status of the floating-point environment

    returns

    ​0​ on success, non-zero otherwise.

25.  def fesetexceptflag(flagp: Ptr[fexcept_t], excepts: CInt): CInt

    Attempts to copy the full contents of the floating-point exception flags that are listed in excepts from flagp into the floating-point environment.

    Attempts to copy the full contents of the floating-point exception flags that are listed in excepts from flagp into the floating-point environment. Does not raise any exceptions, only modifies the flags.

    flagp

    pointer to an fexcept_t object where the flags will be stored or read from

    excepts

    bitmask listing the exception flags to get/set

    returns

    ​0​ on success, non-zero otherwise.

26.  def fesetround(round: CInt): CInt

    Attempts to establish the floating-point rounding direction equal to the argument round, which is expected to be one of the floating-point rounding macros.

    Attempts to establish the floating-point rounding direction equal to the argument round, which is expected to be one of the floating-point rounding macros.

    round

    rounding direction, one of floating-point rounding macros

    returns

    ​0​ on success, non-zero otherwise.

27.  def fetestexcept(excepts: CInt): CInt

    Determines which of the specified subset of the floating-point exceptions are currently set.

    Determines which of the specified subset of the floating-point exceptions are currently set. The argument excepts is a bitwise OR of the floating-point exception macros.

    excepts

    bitmask listing the exception flags to test

    returns

    Bitwise OR of the floating-point exception macros that are both included in excepts and correspond to floating-point exceptions currently set.

28.  def feupdateenv(envp: Ptr[fenv_t]): CInt

    First, remembers the currently raised floating-point exceptions, then restores the floating-point environment from the object pointed to by envp (similar to fesetenv), then raises the floating-point exceptions that were saved.

    First, remembers the currently raised floating-point exceptions, then restores the floating-point environment from the object pointed to by envp (similar to fesetenv), then raises the floating-point exceptions that were saved.

    This function may be used to end the non-stop mode established by an earlier call to feholdexcept.

    envp

    pointer to the object of type fenv_t set by an earlier call to feholdexcept or fegetenv or equal to FE_DFL_ENV

    returns

    ​0​ on success, non-zero otherwise.
