/* Get the architecture dependend definitions. The following definitions

are expected to be done:
|
|
|
|
fenv_t type for object representing an entire floating-point
|
|
environment
|
|
|
|
FE_DFL_ENV macro of type pointer to fenv_t to be used as the argument
|
|
to functions taking an argument of type fenv_t; in this
|
|
case the default environment will be used
|
|
|
|
fexcept_t type for object representing the floating-point exception
|
|
flags including status associated with the flags
|
|
|
|
The following macros are defined iff the implementation supports this
|
|
kind of exception.
|
|
FE_INEXACT inexact result
|
|
FE_DIVBYZERO devision by zero
|
|
FE_UNDERFLOW result not representable due to underflow
|
|
FE_OVERFLOW result not representable due to overflow
|
|
FE_INVALID invalid operation
|
|
|
|
FE_ALL_EXCEPT bitwise OR of all supported exceptions
|
|
|
|
The next macros are defined iff the appropriate rounding mode is
|
|
supported by the implementation.
|
|
FE_TONEAREST round to nearest
|
|
FE_UPWARD round toward +Inf
|
|
FE_DOWNWARD round toward -Inf
|
|
FE_TOWARDZERO round toward 0
