I see no value on it: its programming model is much better than fx-50F/fx-50FH but it isn't solar and for "no solar" calcs there are much older and much better programmable calculators.

The one thing I really like about the fx-5800P is a really small detail that makes a big difference: using ?X without the STO arrow in between to prompt for a value and present the current value as default. It's similar to how INPUT works on the 32S and 42S. It's great for running a program multiple times when you only want to change some of its inputs.

Back on the subject of the fx-50FH and fx-3600P, I worked out a reasonably efficient way to replicate the Int function to get the integer part of a number. You can omit the 0>X term if you know you won't be dealing with negative values.


fx-50FH:

Fix 0:Rnd(X+.5(0>X)-.5(X>0))


fx-3600P:

Fix 0:X+.5(0>X)-.5(X>0):Rnd
