 /*
 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.
