Normal storage function stores answers in decimal form all the time. For storage function after having decimal value on screen press SHIFT then RCL(with STO written on it) then press (-) (with red A written on it) (or press red B, C, D etc.). For recalling that value press RCL then press red letter you previosly stored with.

I assume that by anti-derivative you mean the integral. I believe that you can only calculate definite integrals with this calculator. A definite integral requires that you specify the function e.g ln(x), the variable, x, the numerical value of the lower limit, 0.5 and the numerical value of the upper limit , say 2.
Try this: INT(sin(x),x, 0, pi/2)
This calculator can only give numerical values of definite integrals. If you want to perform symbolic calculations, you shoul look towards some other, more sophisticated Casios Casio ClassPad 330, or the TI Voyage200PLT, or the TI89Titanium. etc.
Hope it helps
