calculating divisors the bash way

divisors.sh

#!/usr/bin/env bash
# This script asks the user for a number and then provides the user with
# all even divisors for it

#----- functions -----
evenDivision() {
        local result=$(( $((100 * $1)) / $2))
        [[ "${result#*0}" == 0 ]]

#----- Application logic -----

echo please provide me with a number
read number

        fi
done

echo these are the even divisors of your number: ${evenDivisors[*]}
