Not only can we compute the inverse, determinant, etc. without rounding errors, but there is useful insight to be found in the numbers themselves- for instance the smallest denominator in the elements of the matrix inverse.

John,
This is a very useful insight! Thank you for sharing it.
Is the ability to work with exact integers and fractions in matrices limited to HP CAS models or do any other HP models have this capability?
