Hi, I just ran into this on a PPC machine:
In [1]: import numpy as np In [2]: np.__version__ Out[2]: '2.0.0.dev-4daf949' In [3]: res = np.longdouble(2)**64 In [4]: res Out[4]: 18446744073709551616.0 In [5]: 2**64 Out[5]: 18446744073709551616L In [6]: res-1 Out[6]: 36893488147419103231.0 Same for numpy 1.4.1. I don't have a SPARC to test on but I believe it's the same double-double type?
