Non-trivial Math

[MickeyBob 1]

I need to do a rather long mathmatical calculation. Is there an instruction that allows multiple mathmatical operations to be done in a single shot? Or do you have to do each operation separately, storing intermediate results in working registers? Tx, MickeyBob

Unless you are using either CS or CJ version 3 CPUs, you must use individual math functions. If you are using one of the new Version 3 CPUs, you can create a function block for your long math calculation.

I'm currently using a CJ1M-CPU21. Is it a "version 3" CPU? Is there a way to easily tell? Tx, MickeyBob
