Casio fx-7200G
The fx-7200G appears to be yet another variant of Casio's classic family of graphing calculators that began with the fx-7000G. The two models seem to differ only in appearance; functionally, they are identical.
The following program demonstrates this calculator's programming model by computing the logarithm of the Gamma function to a high degree of precision using Stirling's approximation:
Ans->X
1->Y
Lbl 1
X>5=>Goto 2
XY->Y
X+1->X
Goto 1
Lbl 2
Xln X-X+ln (2π÷X)÷2+((((1÷1188X²-1÷1680)÷X²+
1÷1260)÷X²-1÷360)÷X²+1÷12)÷X-ln Y
