I think I need a function. One that does this: >> n = 10.0 >> hasattr(n, 'ndim') False >> m = np.float64(n) >> hasattr(m, 'ndim') True np.float64 is fast, just hoping someone had a C-API inline version of np.float64() that is faster. _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
