Hi,

I was using my 34S flashed to recent 3350 calc-full.bin

I had never used the sum (Sigma) and product (Pi) functions.

I coded the identity function f(x)=x trivially:

LBL B

RTN

Then I tried adding 1+2+...+10 with Sigma:

1

[ENTER]

10

[SIGMA]

B

Output: 55 (correct).

Then tried to find 10! instead

1Output: 0 (should be 10!=3628800)

[ENTER]

10

[PI]

B

There is a funny bug in the implementation of PI (product), but not in SIGMA.

Cheers,

Eduardo
