I am trying to use awk and if else statements simultaneously.

Expression in if else statements are evaluated to a whole number and giving wrong output.

I tried this

awk '{if ($4/$3 < 0.35) print "reverse"; else if ($3/$4 < 0..35) print "forward"; else print "unstranded" }' <<< "0 207212663 6541998518 259487717"

This is giving reverse as ouput.
correct answer is unstranded

>Solution :

Invert the logic:

$ awk '{
    if ($4/$3 > 0.35) print "reverse"
    else if ($3/$4 > 0.35) print "forward"
    else print "unstranded"
}' <<< "0 207212663 6541998518 259487717"

Disclaimer: As explained in comments, verify that this fits your needs, and it’s not a false positive output.

Output

forward
