insert a decimal point



hi all. using /bin/sh on an hpux system.

i want to place a decimal in the field 2 charactors from the right (yes, converting to currency). the field lengths are variable. here's what i'm doing:

exec < filename
while read field1 field2
do
field1="echo $field1 | sed 'syntax that will insert . 2 chars before rightmost' "

done

thanks in advance!!!!!

if number may be one digit only, you can use this sed command :

code:
echo "1234" | sed 's/..$/.&/;t;s/^.$/.0&/'  -> 12.23
echo    "1" | sed 's/..$/.&/;t;s/^.$/.0&/'  -> .01
on my aix box, i have a problem with the 't' command inside sed (all the string after t is considered as being the label to branch to). if you have the same problem, you can remove the 't;' part.

nice one, aigles!
