Hi All!

I've had three casio calculators, and it can all display sin(pi/4) as root2/2 perfectly well. However the new fx-82AU Plus II that I bought just works the opposite and gives me long chains of decimal points which is not what I need and I can't change it to fraction form. I found that the answers just generally display in decimal form, for instance if i type 3/2 + root2/2, my Fx-82ES Plus will show 3+root2/2 and Fx-82AU Plus just shows decimals. Is it because its an Australian model or can it be adjusted? Does anyone know any solution?

In the options/menu, is there an option to turn on fractions or not? Have you tried pressing the fraction to decimal button?
