arithmetic in ksh

[daveatwork]

Hi All:
I have a simple ksh script that I would like to add math functions to. So here is the gist of my question:

How can I get 5.2 + 6.3 to show up as 11.5. no matter what I try, typeset, variable declaration, I can't get the decimal value to show up. Any thoughts would be appreciated. thanks, Dave

sum=$(echo "5.2 + 6.3" |dc) vlad
