-If the result cannot be represented (overflow, nan), then
-lrint raises the invalid exception.
-
-Otherwise if the input was not an integer then the inexact
-exception is raised.
-
-C99 is a bit vague about whether inexact exception is
-allowed to be raised when invalid is raised.
-(F.9 explicitly allows spurious inexact exceptions, F.9.6.5
-does not make it clear if that rule applies to lrint, but
-IEEE 754r 7.8 seems to forbid spurious inexact exception in
-the ineger conversion functions)
-
-So we try to make sure that no spurious inexact exception is
-raised in case of an overflow.
-
-If the bit size of long > precision of double, then there
-cannot be inexact rounding in case the result overflows,
-otherwise LONG_MAX and LONG_MIN can be represented exactly
-as a double.
