Floating point problem

[netlearner]

Hi,
I am trying to do division to get percentage. I have used bc to get the float number like 60.0.
however, later on i cant use this same variable in IF statment to make comparison for less than 70. Can anyone help me with this.

Percentage=$(echo "scale=1;(( $Rcount / $Fcount ) * 100 )" | bc )


if [ $Percentage -lt 70 ]
then
echo $Percentage
fi

You may ask bc, whether the result is less than 70:

Percentage_lt_70=$(echo "scale=1;(( $Rcount / $Fcount ) * 100 ) < 70"  | bc )
echo $Percentage

echo $Percentage_lt_70 then of course ...
return will be 0 for false and 1 for true.
