Less than is not working properly in bash if the value is 10.00

Question

We are getting an unexpected output while running the following codes

PYLINT_SCORE=10.00
THRESHOLD=7

if [[ $PYLINT_SCORE < $THRESHOLD ]]; then
    echo "Your Code is not meet the threashold value";
else
    echo "Your Code meet the threashold value";
 fi;

Here we are getting "Your Code is not meet the threashold value"

But if run the following code we are getting the correct output like "Your Code meet the threashold value"

PYLINT_SCORE=9.99
THRESHOLD=7

if [[ $PYLINT_SCORE < $THRESHOLD ]]; then
    echo "Your Code is not meet the threashold value";
else
    echo "Your Code meet the threashold value";
 fi;
