Saturation is a real thing: lots of DSPs use Q-format fixed-point integer maths with saturation. It's not designed to not have errors, it's a way to detect overflows without floating point capability. You can't always just throw an error in some hard real time systems (though you obviously need to take care of saturated results "carefully", which depends on what you're up to).
