divided by 0 problem
Hi!

i have a new shell script that will compute for a value...

Code:
 
a = b/(b+c)
c = d/(d+e)
print b" "a" "d" "c

but there will be an instance that either b+c or d+e will be "0".... if b+c or d+e is "0" it will print "#NA#...

pls help me... thanks!

This is your code or this is what you want? Does not look like a valid code?

it's a part of an awk... i used awk to get the corresponding values for the variables a, b, c, d & e..

which shell ? Looks more about awk.
You must test always divide by 0 in every tools. What is value of a if b+c is 0 ?

if the dividend yields a value of "0", then the answer should be "#NA#"

---------- Post updated at 04:35 PM ---------- Previous update was at 04:32 PM ----------

Code:
if((b+c) = "0")
{print b" ""#NA#"" "d" "c}
if((d+e) = "0")
{print b" "a" "d" ""#NA"}

but it yields an error of "you can't divide by zero"

if your dividends is 0, don't do the math just replace it with #NA#
