Programming Exercise (HP-15C, 15C LE - and others)

[Thomas Klemm]

Now I'm confused.

10000.001
\(\sum\) 00
This counts down from 10000 to 1. Isn't that what we want in (b)?

Here's another solution:

Code:

LBL 00
EVEN?
+/-
1/x
END

That's a lot more that I had expected.

(03-22-2014 12:47 PM)Gerson W. Barbosa Wrote:  Item (b) would be something like

Code:


LBL A
+/-
RCL+ 00
(-1)ˣ
RCL/ L
END

10001 STO 00
10.001
\(\sum\) 00
+/-

I get: No such Label
Even using \(\sum\) A doesn't make much sense.

Cheers
