How to see results as fraction/roots - BorisDrovesky - 09-16-2017 12:17 AM

Hello.
Im new to the HP Prime, Im mostly using the matrix and vectors functions.
My issue is as simple as not being able to have my results shown as fractions and/or squareroots,etc.
For example, lets say I get a matrix like these one (an orthogonal matrix):

If I introduce it into the HP the values will be shown as decimals (i.e. -0.70710678118), etc. The thing is I need the results (for example if I calculate the square of the matrix, or whatever) to be shown as fractions and/or in exponential notation(i.e. -1/(2^(1/2)). Otherwise, using the calculator is a total waste of time.
Is there any way I can get that?

Thanks in advance.

Boris

To work with exact values you need to be in CAS mode.
