read actual matrix value without rounding off

I have computed a matrix that "seems" to have numbers with very high precision, for instance, the number 1.000 in the matrix below

However, when I try to read the number r(1,3), I got a number which is rounded off to 1 and I need it with full precision.

Is there a way to prevent this automatic rounding while reading the values of a matrix?

r =

0.0000 0.0000 1.0000

-0.9135 0.4067 0.0000

-0.4067 -0.9135 0.0000

>> r(1,1)

ans =

1.7006e-09

>> r(1,2)

ans =

3.9261e-10

>> r(1,3)

ans =

1

Use the format function to change how the matrix is displayed. This does not change the values that are stored in the matrix, just how they are displayed.
