My point is: as a programmer, you should always care how your value is handled. All variable types have limitations, edge cases, and resource demands (infinite capacity big-int representations are slow and memory intense, even if they never overflow or underflow.) KNOW what your code is doing with the value.

I'm O.K. with API style functions accepting all kinds of inputs and dealing with them in a predictable way once called, but if you're writing code that handles values, once you have been assigned those values you should be getting, deterministically, the same result every time.

Otherwise, you're like those kids in programming class writing while loops with floating point control variables that increment +0.1 per loop, thresholded to stop at v >= 100.0
