Hi, We just spend some time debugging some numpy image analysis code where we finally noticed that our file was byte-swapped ;-). Even though we got much crazier numbers, the test below already shows one bug in the a.real.max() line. My numpy.__version__ is '1.0b3.dev3015' and this is run on pentium (little endian) Linux (both 64bit and 32bit version give same results):
>>> a = N.arange(4, dtype='>c8') >>> a [ 0. +0.00000000e+00j 0. +1.00000000e+00j 0. +2.00000000e+00j 0. +3.00000000e+00j] >>> a.max() (3+0j) >>> a.real.max() 0.0 >>> a.imag.max() 4.60060298822e-41 >>> >>> a = N.arange(4, dtype='<c8') >>> a.max() (3+0j) >>> a.real.max() 3.0 >>> a.imag.max() 0.0 >>> Can someone test this on a newer SVN version ?
