Shell script : value under 1 (0,0...) is accepted as 0?
Hi all,,

I have this script
Code:
ctr=$(( 1/1000 ))
while [ 1 ]
do
  echo $ctr >> test.txt
done

However, it puts 0 instead of 0.001

How can I put 0.001 in the text file?

Thank you

Could this help you ?
Code:
 ctr=$(awk 'BEGIN{print (1/1000)}')

OR
Code:
 ctr=$(echo 'scale=3;1/1000' | bc)

If you can use ksh93 or a shell that supports declaring variables as floats:
Code:
$ cat efs
#!/usr/dt/bin/dtksh

typeset -F a=1
typeset -F b=1000

ctr=$(( ${a}/${b} ))

print $ctr
$ efs
0.001
$
