for loop - BASH: iterate over a list of floating numbers in decrement -

what want similar python codes beneath, while variables start, end, , spacing float numbers , start > end.

for in numpy.arange(start, stop, step):      print

or,

for in numpy.linspace(start, stop, num):     print

i know awk handy (see second answer in question).

num=$(awk "begin{for(i=${start};i>=${stop};i-=${step})print i}")    n in $num     $n  done

but, how realize iteration on list of floating numbers in decrement in bash without using awk?

thanks !

you may use seq

seq [option]... first increment last
