Question

I have a problem with the following piece of code

THRESH_SERIE=("1" "5E-1" "1E-1" "5E-2" "1E-2" "5E-3" "1E-3" "5E-4" "1E-4") 

for ((i=0;i<${#THRESH_SERIE[@]};i++))
do

    let thresh=$(echo ${THRESH_SERIE[$i]})
    $EXEC 1 $N ${thresh} 0 0 >> $OUTPUT
done

If I try to run the script it will return an error like the following for each value in the array:

/bench_new.sh: line 40: let: thresh=5E: value too great for base (error token is "5E")

I’ve tried also to use floating point numbers (like “0.1”), but it gives a different error. How can I solve this?

Answer 1

No particular reason for the array here (other than they’re “fun” to play with):

THRESH_SERIE="1 5E-1 1E-1 5E-2 1E-2 5E-3 1E-3 5E-4 1E-4" 

for thresh in ${THRESH_SERIE}
do
  $EXEC 1 $N ${thresh} 0 0 >> $OUTPUT
done
