This is a good scientific calculator that can do a lot, but things in the realm of a CAS (Computer Algebra System) are beyond its capabilities.

SOURCE: my casio calculator is giving answers always in fraction form. I need to get the answers in decimal form (my calculator is fx-991ES)

To convert a single answer from symbolic to decimal, press the S--D key (just above the DEL key). To have all answers come out in decimal format, press SHIFT MODE 2 to switch to the LineIO mode.

Press the Shift/Mode key and set the Input/Output to MathIO.

I have to buy Casio FX-991W Plus. No one has it. I checked eBay and the Casio web-site. I need that one. where can I get it from?


Hi,
If you cannot find it, buy an FX-991ES. It is solar-powerd and it has the natural text-book display, which is a novelty in calculators.
I know that Staples carry the FX-991ES.

Hope it helps.
