Fi Statement Syntax Error

I am trying to execute the following code in a bash script to determine whether or not a number is greater than 1 or less than 1.

Bash Code:

weight_check=`bc <<< "(.4+.4+.1+.1+.2)"`
if [[ ${weight_check} -lt "1.0" ]] || [[ ${weight_check} -gt "1.0" ]];
then
    echo "Incorrect Weights!"
    exit 0
fi

Error:

syntax error: invalid arithmetic operator (error token is ".2")

The sum of ${weight_check} equals 1.2 but, the bash script doesn't see this...

The input numbers in ${weight_check} will change so, I need this if/then/fi statement to be able to act dynamically.

Is my if/then/fi statement set up incorrectly?

How about an if/then/elif/fi statement. So `if {weight_check} -eq "1.0" then ... elif echo "Incorrect weights!" fi` – liam_g Jan 08 '16 at 17:13
@Tom Fenech marked this as a duplicate post but, I just tried the answers that were given in that post and they did not solve my problem... – Aaron Perry Jan 08 '16 at 17:28
Additionally, I tried your method @liam_g and it did not work. – Aaron Perry Jan 08 '16 at 17:31

Do the test in `bc`, which will result in 0 or 1. You can test that in bash: `if (( $(bc<< – rici Jan 08 '16 at 17:40
I am now receiving the following error: `syntax error near unexpected token fi` – Aaron Perry Jan 08 '16 at 17:41
