Hi. I'm doing a script that will calculate for total number of minutes or average min per call in asterisk. Me problem is that, when I do the math, It never resulted with decimal numbers which I really need. Here is an example of what I'm calculating

70/60/5

where 70 is the total usage of call in seconds.

where 60 is equivqlent to 1 min.(i have to divide 70 by 60. answer would be 1.16

where 5 is the total successful calls. I have to divide that total minutes(1.16)to 5 calls
that would 0.233

The script is prompting just 0.
I need the 0.233

How can I do this in my script?

Here is my example script.

TMECNSUMED=`cat master.txt | sed 's/ /\t/g' | grep "ANSWERED" | awk '{print $2}'`
seconcdr=0 #controls for the i
b=0 #Variable counter for row
for i in $TMECNSUMED
do

(( seconcdr = $i + $seconcdr ))
(( b = b + 1 ))
done

(( seconcdr= ($seconcdr/60)/$b))

Pleasehelp me on this thanks

if you want variables in points then define them as float.
float $variable
