they are computer engineering by-products. Are quirks and
idiosyncracies. Check out a advanced lang such as Mathematica. There,
one can learn how the mathematical concept of integer or real number
are implemented in a computer language, without lots by-products of
comp engineering as in vast majority of langs (all those that chalks
up to some IEEEEEEE. (which, sadly, includes C, C++, java, perl,
python, lisp, and almost all. (lisp idiots speak of the jargon “number
tower” instead IEEEE.) (part of the reason almost all langs stick to
some IEEEEEEEE stuff is because it's kinda standard, and everyone
understand it, in the sense that unix RFC (aka really fucking common)
is wide-spread because its free yet technically worst. (in a sense,
when everybody's stupid, there arise a cost to not be stupid.)))).
