hi,

I want to do a basic thing but without succes:

if a=1232, let nb_nb=4 (the number of digits)

for i from 1 to nb_nb, I want the following results:

i=1 => res=1 (first digit of a) and NOT the number 01 (with a zero in

front of the 1)

i=2 => res=2 (same thing)

i=3 => res=3

i=4 => res=2

I tried a few things, like convert the number in array (it seems to keep

the “0” in the result)…

do you have a solution?

You could try

a.to_s.split(//).collect {|s| s.to_i}

and extract nb_nb elements.

It’s not clear to me what you want to do, but maybe this will help:

a=1232

str = a.to_s

p str

–output:–

“1232”

digits = []

str.length.times do |i|

digits << str[i, 1]

end

p digits

–output:–

[“1”, “2”, “3”, “2”]

res=1 (first digit of a) and NOT the number 01

1 and 01 are the same *number*.
