det FUNCTION IS HAVING A VERY ANNOYING BEHAVIOR,GIVEN THE ATTACHED
MATRIX FOR EXAMPLE
IF I TRY TO GET THE DETERMINANTS WITH TWO DIFFERENT METHODS:

sage: M=load(PATHTOFILE + '/M.sobj')
sage: M.det()
6.49037107316853e32
sage: from numpy import linalg
sage: linalg.det(M)
-1.5055380070396349e-05

THE SECOND RESULT IS CORRECT (THE MATRIX IS SINGULAR).
THE DEFAULT det FUNCTION SEEMS TO OVERFLOW WITh A MATRIX OF JUST 20
ROWS? IS THIS A BUG?
