Experience points leveling curve

Hi everyone.
I was thinking of implementing an experience leveling curve for my game, so that I can visually experiment with how many experience points are needed per level.
I was wondering if there was a more “efficient” way than using a float curve, or if there’s any way to limit it to “discreet” values, as I would only need for instance 50 points on the curve, instead of “infinite” ones that it would of course give me.
Thank you. :slight_smile:
