Express a square root form in the result of Matlab

How I can express a square root for example sqrt(2) in the result of a Matlab computation instead of express the irrational number. For example: sqrt(2) the result should be

2^(1/2)

or

sqrt(2)

instead of 

1.4142

Thank in advance!

If we look at the first two examples on the web page Symbolic Math in Matlab we see that the way to get what you want is

sqrt( sym(2) )

which returns

ans =
2^(1/2)

As the page says,

The key function in Matlab to create a symbolic representation of data is: sym() or syms if you have multiple symbols to make.
