Just for completeness some more tests using pythonmath/scalarmath for int,
float or both (in usec per loop):
sin - array mod - array xx
(a) - (no import of numpy.core.scalarmath)
numpy 0.9.9.2800 152 76.5
numpy 0.9.9.2800 + math 50.2
(b) - (use_pythonmath(xx))
numpy 0.9.9.2800 107 60.4 (int)
numpy 0.9.9.2800 + math 32.7
numpy 0.9.9.2800 148 43 (float)
numpy 0.9.9.2800 + math 50.7
numpy 0.9.9.2800 109 26.5 (int, float)
numpy 0.9.9.2800 + math 32.4
(c) - (use_scalarmath(xx))
numpy 0.9.9.2800 149 77.1 (int)
numpy 0.9.9.2800 + math 50.7
numpy 0.9.9.2800 147 74.3 (float)
numpy 0.9.9.2800 + math 50.7
numpy 0.9.9.2800 148 73.5 (int, float)
numpy 0.9.9.2800 + math 50.8
Maybe use_pythonmath(int, float, complex) should be set as default?
Many thanks,
Steffen
