the fx-82l variation came fitted into a hard
plastic case which completely enclosed it protecting it well.
this time, casio had realised that the batteries never ran out, so this
model had them fixed inside the machine. you could replace them, but it
involved taking the machine apart.
looking closely reveals that this model is actually a lot better than
its basic fx-82 counterpart. for one thing the screen display is slightly
bigger and clearer. the keys are more styled and easier to operate and
there are new functions added as well as the advertised
"fraction". RND, RAN#, HYP and %.
