Weird result with Matrix determinant
I wanted to calculate the determinant of the matrix
$$\begin{pmatrix} 1 & 0 & 2 & 8 \\ -2 & 1 & 1 & 5 \\ 6 & 3 & 5 & -4 \\ 10 & 4 & 3 & 0 \end{pmatrix}$$ Using Standard number format, Prime Home says -647,000000002 Prime CAS says -647 Home is pretty close but what kind of algorithm can produce such a funny result to calculate a determinant with only integers? Other question is: do we have an explanation for Floating and Rounded Number Formats? Those are recent additions not documented in the user guide. |
