12c platinum again - from comp.sys.hp48 Message #1 Posted by Gene on 19 May 2003, 10:05 a.m.
Saw this over the weekend. It confirms the "bug" in the solution for the interest rate in an annuity. I had called this to HP's attention, but doesn't seem like they could or wanted to fix it. --Gene

There is something very strange about the new 12c platinum.
Resolving for i is, one could say, no longer possible. My one displays "running" for so long I have to press the ON key. I have tried many simple examples now.
If indeed it does resolve, before running bateries flat, it
must take a very long time.
Oh, it did work n=10 i=10 pv=100 fv=0 solve for pmt=-162.745
resolve for i ... it seems to take 40 seconds. [Gene: Note, on my 12c platinum, it returns 10 for i almost instantly...however, if I store 0 into i and then resolve for it, it takes about as long as the poster indicates]
On the classic gold 12C it takes 4 seconds.
This is, believe me, an example that is favourable to the 12c platinum.
Unfortunately this does make it a returnable item, unless one really likes bugs like this.
