Hi, Sorry for my confusion, but I noticed (as a result of the discussion here [1]) that np.rint and the fallback C function [2] seem to round to even. But - my impression was that C rint, by default, rounds down [3]. Is numpy rint not behaving the same way as the GNU C library rint?
In [4]: np.rint(np.arange(0.5, 11)) Out[4]: array([ 0., 2., 2., 4., 4., 6., 6., 8., 8., 10., 10.]) In [5]: np.round(np.arange(0.5, 11)) Out[5]: array([ 0., 2., 2., 4., 4., 6., 6., 8., 8., 10., 10.]) Cheers, Matthew [1] https://github.com/nipy/dipy/issues/1402 [2] https://github.com/numpy/numpy/blob/master/numpy/core/src/npymath/npy_math_internal.h.src#L290 [3] https://www.gnu.org/software/libc/manual/html_node/Rounding-Functions.html _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@python.org https://mail.python.org/mailman/listinfo/numpy-discussion
