+   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		division 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
