(50g) OEIS A014263: Integers with Exclusively Even Digits - Gerald H - 08-27-2017 03:03 PM
For integer input N the programme returns the Nth integer composed solely of even digits. For more info see http://oeis.org/A014263 Code:

If "Z5_" means BINT5, then either I made a typo or there's a bug somewhere, because all it does is return 2x for any input x. E.g. Input 153, it returns 306 (contains an odd digit; answer should be 2206). BYTES on the compiled program returns 75 #48F7h.

It works fine for me. I have added a compiled version to my site here: http://www.hpcalc.org/details/8653 RE: (50g) OEIS A014263: Integers with Even Digits - Joe Horn - 08-27-2017 11:55 PM

"Z5_" does NOT mean BINT5. It means ZINT 5, which I could only discover by downloading the copy from Eric's site and disassembling it. The built-in assembler does not know what "Z5_" means, and neither did I. Suggestion: Use HP 50g ASM notation, and include the checksum (which is #FB66h for the above program), when posting System RPL source code. Thanks in advance! By the way, Gerald, I really like the algorithm used here: Convert to base 5, then double that number as a base-10 number. Very cool!

Sorry, I forget that eg Z5_ is not standard, although Eric Rechlin must use the same tool as me. As for your 2 suggestions - wilco. Yes, a neat algorithm, thanks to http://oeis.org/wiki/User:Franklin_T._Adams-Watters for his insight. RE: (50g) OEIS A014263: Integers with Even Digits - 3298 - 08-28-2017 11:46 AM
Z5_ is an unsupported entry - the standard Extable doesn't have it (as far as I know) but there are modified Extable versions that include it along with many other unsupported entries. I'm using the one that comes with Emacs 2.11a and it compiles Z5_ just fine. RE: (50g) OEIS A014263: Integers with Exclusively Even Digits - Gerald H - 08-29-2017 10:24 AM
