Casio FX-850P
Sleek and elegant, the fx-850P is a fairly modern BASIC-programmable handheld calculator that sports a potentially useful feature: a comprehensive equation/function library. Perhaps not a terribly exciting machine, but with this built-in library, a large display, and a comfortable amount of memory make this calculator, it is nevertheless a pleasure to use.
The programming model of the fx-850P is demonstrated by the following example, computing the logarithm of the Gamma function:
10 INPUT X 20 G=1 30 IFX>5GOTO70 40 G=G*X 50 X=X+1 60 GOTO 30 70 S=1/1188/X/X-1/1680 80 S=S/X/X+1/1260 90 S=S/X/X-1/360 100 S=S/X/X+1/12 110 G=X*LNX-X+LN(2*PI/X/G/G)/2+S/X 120 PRINT G;EXPG
