Hi, I'm new at Linux shell programming so I could use some help. I need to make a 20thdecimal convertor. Is just like hexadecimal, the only difference is that hexadecimal goes from 1-9 and A-F, and I need this one to go from 1-9 and A-J.
I got some already but I get endless loop, please take a look.
Code:
echo -n "insert number to be converted: "
read decimal
until [ $decimal -eq 0 ]
do
div=`echo $decimal /20 | bc`
res=`echo "$decimal-$div * 20" | bc`
echo $res $div
done
At this point I get the two number that I need, then I just add some labels to let it know that A= 11, B= 12, etc. The thing is I cannot stop the loopAny ideas aprecciated.
I used this Hexadecimal convertor as started and just changed the base from 16 (hexadecimal) to 20 (the one I desire) on lines 6,7.
Code:
echo -n "numbers to be converted: "
read decimal
while [ $decimal -gt 0 ]
do
div=`echo $decimal /16 | bc`
res=`echo "$decimal-$div * 16" | bc` decimal=$div
if [ $res -eq 10 ] ; then
res=a
if [ $res -eq 11 ] ; then
res=b
elif [ $res -lt 9 ] ; then
res= $res
fi
hex= $res $div
echo $hex
