Sharp EL-5103S
The Sharp EL-5103S appears to be a smaller, pocket sized version of the EL-5100S calculator. The programming model is the same "AER" (Algebraic Expression Reserve) with a somewhat smaller storage capacity; only 48 steps instead of 80. Like the EL-5100S, the EL-5103S offers no branching or conditionals, so loops or iterative programs cannot be entered.
The expression below calculates my favorite example, the Gamma function, or to be more precise, its approximation using Stirling's formula. For arguments above 4, the accuracy is at least 6 digits:
1;f(A)=√2π×AYx(A-.5)×e(1÷12A-A-1÷360A)
