Summation based benchmark for calculators

[TheKaneB]

Sharp EL-5120 Solver
With 100 iteration it runs for approx. 36 seconds, giving a result of 139.297187 (all digits correct according to my HP Prime).
It lacks proper loop instructions, so I used a manual counter with a IF ... GOTO instruction

Code:


X1 = 1
A1 = 0
LABEL A
A1 = A1 + 3 <x-root-of>(e^(sin(atan(X1))))
X1 = X1 + 1
IF X1 <= 100 GOTO A
PRINT A1
