Here's an array a = [[ -2.66453526e-15, 4.49564793e-02, 1.14401980e+00], [ 2.02475000e+00, 2.06970648e+00, 1.14401980e+00], [ 2.02475000e+00, 4.49564793e-02, 3.16876980e+00], [ -2.66453526e-15, 2.06970648e+00, 3.16876980e+00], [ -2.66453526e-15, 4.49564793e-02, 5.19351980e+00], [ 2.02475000e+00, 2.06970648e+00, 5.19351980e+00], [ 2.02475000e+00, 4.49564793e-02, 7.21826980e+00], [ 0.00000000e+00, 2.02475000e+00, 7.08662500e+00]] Now, call array_repr(a, precision=12, suppress_small=True) which gives the output array([[-0. , 0.0449564793, 1.1440198 ], [ 2.02475 , 2.06970648 , 1.1440198 ], [ 2.02475 , 0.0449564793, 3.1687698 ], [-0. , 2.06970648 , 3.1687698 ], [-0. , 0.0449564793, 5.1935198 ], [ 2.02475 , 2.06970648 , 5.1935198 ], [ 2.02475 , 0.0449564793, 7.2182698 ], [ 0. , 2.02475 , 7.086625 ]]) * Since the flag 'suppress_small=True' is used, I'd expect a '0.' instead of a '-0.' or maybe this is intentional. * Also, wouldn't '0.0' instead of '0.' be more readable (and there's certainly space enough to add it)?
