Re: [Numpy-discussion] A couple more Numeric incompatibilitiesand a possible bug
Actually, this reproduces the problem:
from numarray import * from numarray.objects import * abs(-1.) ObjectArray(1.0) abs(-1) ObjectArray(1)
Please ignore this bit of my previous message:
abs(-1) ObjectArray(1)
Something in my environment (probably me) got a bit confused.

I'm guessing, but I think you would like to see:
abs(-1.) 1.0 abs(1) 1
If so, this is a bug. Two things are going on: 1) numarray.objects redefines abs() 2) Internally, numarray has a concept of "rank-0" arrays which it uses to represent scalars. Apparently, numarray.objects lacks the extra code to filter rank-0 arrays out (convert back to scalars) as is done with numerical arrays. I logged this as a bug on Source Forge and it will be fixed for 1.0. Regards, Todd -- Todd Miller <jmiller@stsci.edu>
