Summation based benchmark for calculators

[Mjim]

Just recently got hold of a Casio fx-50F (introduced 1987, but from the catalogues, still sold in 2000 and perhaps even later). Programming is limited to 29 steps (each single digit is counted as a step, so you want to set up constants in memory pre-program).

I split the program between 2 program slots P1 & P2, though you don't really need P1, as [FMLA][A] just maps to memory 1, so just send the value for n to this memory before starting the program P2.

P1 for the input and to clear the memory:

Code:

[FMLA][A]
[AC]
[SHIFT][Min]

P2 for the summation:

Code:

[Kout][1]
[SHIFT][tan^-1]
[sin]
[SHIFT][e^x]
[SHIFT][x^(1/3)] <---cube root
[M+]
[1]
[SHIFT][Kin][-][1]
[Kout][1]
[SHIFT][x>0]
