@KitRedgrave because gnu utils tend to be horrifyingly overcomplicated as well as being originally written to avoid accusations of copying then-proprietary unix sources

i decided to make the whole thing infinitely more simple by dropping floating-point entirely, because i'll only be using it as a for-loop replacement thing in ksh scripts
