[Editor's note: fixed limit on user request] As a mathematician, 3/0 == +INF IS JUST WRONG. You can't just assume 3/0 == lim_{x->0+} 3/x, which is +INF indeed, because division IS NOT A CONTINUOUS FUNCTION in x == 0. Also, 3/0 == +INF ("positive" infinity) while -3/0 == -INF ("negative" infinity) requires the assumption that 0 is a positive number, which is just as illogical as it looks like. The fact that a warning is emitted is good, but it should definitely equals to NaN. ±INF is just illogical (and arithmetically wrong). Except for this "detail", looks an amazing update, can't wait to test it even further! Cheers, P. --was-- As a mathematician, 3/0 == +INF IS JUST WRONG.
