Comment (by jmroot):

 All floating point calculations are inherently inexact. There is no
 "right" and "wrong" behaviour you're demonstrating here, just (very
 slightly) different.

 To put it another way, there is a roughly 50% chance when casting //any//
 floating point number to an integer type that you will get a result that
 is not the integer that is closest to the original value, but one less
 than that. That's just how truncation works, and is why you don't want to
 do it, on any platform.
