No.

I get a problem with using longdouble as that is the dtype that causes 
the  TestPower.test_large_types to crash.
Also, np.finfo(np.float128) crashes. I can assign and multiple 
longdoubles and take the square root but not use the power '**'.
 >>> y=np.longdouble(2)
 >>> y
2.0
 >>> y**1
2.0
 >>> y**2
crash
