Say you have this numeric variable that can be set by the user but you never want it to leave a certain range when it gets printed. How could you use parameter expansion such that it will never expand outside of that boundary? Thanks

Bah nevermind looks like the ternary operator is the answer and not parameter expansion
I was running this script every so many seconds using sleep but on the first attempt I didn't want it to sleep less than 60 seconds, but the user could specify higher. On subsequent attempts I didn't want the user to specify lower than 20s.
So for the first attempt I have something like:
sleep $(($frequency > 60 ? $frequency : 60))
and subsequent attempts:
sleep $(( $frequency > 20 ? $frequency : 20))
