Both of them really limited, but there are little tricks to improve these capabilities, eg. how to use stat registers to increase the number of storage space (this program use ALL registers to store CFs, but use the stat regs and Ans for looping and calculating NPV and iterating IRR): A very accurate Sunrise/Noon/Sunset program  you can see a little analemma curve installed inside the hard cover for calculating anywhere, anytime, eg. during a hiking: Youtube video With fx3650P you can write (I know, because I wrote) a little solver and with the d/dx() and integrate you can solve any root finding, extremum finding and integral range finding (eg. zscore statistics) and separable differential equation solver with these calculators (and yes, this is accurate because of the implemented integral routine).
