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

[Dave Britten]

I ran this through my Casio fx9860G Slim:

Code:


0\->X
For 10000\->C To 1 Step -1
X+C\-1*(-1)^(C+1)\->X
Next
X

This prints 0.6930971831 in just under a minute. It's definitely one of the faster models available. Too bad the interface design is so heavily modal - it's much too cumbersome for day-to-day use. I don't know why Casio has clung to that paradigm for so long.
