MultiFactorial using 19BII Solver Message #1 Posted by Bill (Smithville, NJ) on 1 Mar 2007, 3:23 p.m.
Yesterday, Egan posted how to calculate multiFactorials, which I had never even heard of before his post. See following link

Egan had posted a HP15C program that would calculate it.
I've been playing around with the solver on the HP19BII and thought I'd give a try at translating his 15C program to a solver equation.
I came up with the following:
MF = SIGMA(K:1:
IF(X=N OR N=1:1:(X/N)+1):1:
IF(K=1:0*L(M:X):0*L(X:XN)+0*L(M:G(M)*X)))
+ IF(N=1:FACT(X):G(M))
Just enter X and N and press MF to solve.
I'm still trying to learn how to use the solver, and this is my first try with the SIGMA function. So would appreciate any suggestions, comments, etc on how to do it better.
Thanks,
Bill
