Financial functions on current version of Numbers?

What happened to the Functions such as PV, FV, amortizing schedules, etc that used to be on the iMac version of Numbers? I haven't done much work requiring financial functions the past year or so but now that I want to update some older spreadsheets I did (using Numbers) a couple of years ago, all Numbers wants to offer me are simple arithmatic fiunctions like add, average, subtract and a couple others. My iMac is up to date with latest operating system version 13.4.1. What's going on? Am I the last to learn that Apple numbers has been dumbed down beyond belief?
