I figured it out.
I was already headed the right direction by using something like this…
<button text=“Hold Enter” ontap=“enterhold” ondoubletap=“enterrelease” />
But for whatever reason it seems to ignore a double tap to release it, maybe I’m just too slow on tapping lol. I changed it to onhold=“enterrelease” and it works like intended.
Same, I’ve always just rounded up. Even when it comes to things like .50¢ I still just round it up to the next dollar.
