One way is to use less accurate floating point numbers.
This can be done using
- the method
change_ringof a matrix - the function
RealField
Define a matrix:
sage: a = matrix(RR, 3, [j * 100./99 for j in (1 .. 9)])
sage: a
[1.01010101010101 2.02020202020202 3.03030303030303]
[4.04040404040404 5.05050505050505 6.06060606060606]
[7.07070707070707 8.08080808080808 9.09090909090909]
Change to 20-bit floating point numbers
sage: b = a.change_ring(RealField(20))
sage: b
[1.0101 2.0202 3.0303]
[4.0404 5.0505 6.0606]
[7.0707 8.0808 9.0909]
