Casio fx-7000GA
The fx-7000GA is a minor variant of Casio's classic graphing calculator, the fx-7000G. Apart from slight differences in housing style, the two models appear to be identical.
The following example is an implementation of the Gamma function using the classic recipe from the book, Numerical Recipes in C:
"X=":?->X 1->Y Lbl 1 X>=0=>Goto 2 XY->Y:X+1->X Goto 1 Lbl 2 e(ln ((1+(76.18009172+9.5E-9)/(X+1) -86.50532033/(X+2)+24.01409824/(X+3) -1.231739572/(X+4)+1.208650973E-3/(X+5) -5.395239384E-6/(X+6))× √(π×2)/X)+(X+.5)× ln (X+5.5)-X-5.5)/Y
