Why? How should I construct scripts from that using variables, i.e.
use typeset -s -E svar; printf 'typeset -s -E var; for ((var = %s; var
< %s; var+= %s)); do myfunc var; done' ${svar.MIN} ${svar.MAX}
$((2**24)) | source /dev/stdin

That part doesn't make sense. Like functions nextafter() and
nexttoward() the constants for a variable depend on a type for at
least minimum, maximum and epsilon or they are not usable.
