🙂

The built-in filterNaN in Prime4 throws the same error as in P9.

Actually the bug is already present in Mathcad 15 😞

In that case we know who to blame: PTC was responsible for Mathcad 15 and all versions of Prime.

I'm responsible for the implementation of the filterNaN function in the PrimeExpress library.

Note that it has this peculiarity:

(It doesn't do vectors, yet)

I now see how to mend that (the dirty way)
