内容
Concrete example of int/int not being correctly rounded on systems using x87 instructions: on those systems, I'd expect to see 1/2731 return a result of 0.00036616623947272064 (0x1.7ff4005ffd002p-12), as a result of first rounding to 64-bit precision and then to 53-bit. The correctly-rounded result is 0.0003661662394727206 (0x1.7ff4005ffd001p-12).
