SOURCE: Why does it solve in fractions?
The calculator has two Input/Output modes: the default MthIO (new) and the old LineIO.
If you use the default MthIO you can let your calculator perform the operations in exact arithmetic. When you obtain the end result, you can easily convert a fraction/radical result into a decimal one by pressing the [S<=>D] key, or press [SHIFT][=] instead of [=].
However if you do not care about the MthIO and its nifty functionalities, you can configure your calculator to use LineIO.
To set LineIO press [SHIFT][MODE][2:LineIO]
