Here is a quick and dirty way of converting a decimal number to hexadecimal, octal, or binary. Below is an inline script followed by a normal shell script file. There are some non-looping examples toward the end of the post.
# ksh
# for i in 100 102 103 104 105 110 1000

> typeset -i8 oct
> oct=$i
> print $i equals $oct in octal
>
> typeset -i2 bin
> bin=$i
> print $i equals $bin in binary

> done
100 equals 8#144 in octal
100 equals 2#1100100 in binary
102 equals 8#146 in octal
102 equals 2#1100110 in binary
103 equals 8#147 in octal
103 equals 2#1100111 in binary
104 equals 8#150 in octal
104 equals 2#1101000 in binary
105 equals 8#151 in octal
105 equals 2#1101001 in binary
110 equals 8#156 in octal
110 equals 2#1101110 in binary
1000 equals 16#3e8 in hexadecimal
1000 equals 8#1750 in octal
1000 equals 2#1111101000 in binary
Or put it in a script and specify an argument list via CLI
# vi my_converter.ksh
#!/bin/ksh
echo Add an argument list
exit
fi
hex=$i
print $i equals $hex in hexadecimal
oct=$i
print $i equals $oct in octal
bin=$i
print $i equals $bin in binary
done
:wq!
