fx8700g.jpg (28275 bytes)The fx-8700G is another graphing calculator from Casio. It has greater memory capacity, but it is otherwide functionally identical to the fx-7700G.

The program below demonstrates the calculator's programming model by computing the Gamma function:

"X=":? -> X
1 -> Y
Lbl 1
X >= 0 => Goto 2
X×Y -> Y:X+1 -> X
Goto 1
Lbl 2
e(ln ((1+(76.18009172+9.5E-9)/(X+1)
  √(π×2)/X)+(X+.5)× ln (X+5.5)-X-5.5)/Y
