Re: Cons (predominantly) and pros (if any) of agile development

I lean towards the "agile is for the lazy developer" line. Even though I'm a developer and our approach is far more agile than most. A high level of self motivation is beneficial.

Re: Is there a fixed goal and objective for Free42?

The reported problem is:
WP34S emulator: (-6.2-7.6i)! = -20.3658 + i1.2046
WolframAlpha: (-6.2-i7.6)! = -9.8594e-11 + i3.2965e-12
The 34S is correct for positive values. My guess is the gamma function reflection formula is awry in the complex case.

Re: Is there a fixed goal and objective for Free42?

I have been tempted to add additional functions to Free42, I know how but I've not managed to get time yet.

For anyone interested in some hard core mathematical programming, there is a problem with the WP 34S's complex gamma function which I haven't managed to get to....

Re: [POLL] Compiler for DM15L ?

If possible, I'd go for Lua -- small and lean VM, JIT compilation is available for ARM CPUs and it is fast (even without that).
It's also a very simple but expressive language.

Re: DM42 program with EVERY instruction?

Look at the Free42 source code?

For import/export it uses an extension of the HP-41 coding.
Internally, it is very different.

Re: Little Problem with Complex Mathematics on Calculators

While there is an infinite number of integer values, it seems logical that the also infinite number of rational numbers is larger, and real numbers larger still. It isn't logical. There are the same number of rational numbers as there are integers, this we proved by Cantor. There are more real numb...

Re: Small program to print all XTOA caracters on the printer

I just noticed that the original program omits the divide character (#0).

Re: Small program to print all XTOA caracters on the printer

Inspired by this program, I've done one that prints the characters out in a 16 by 16 grid. Attached.
