Hi
I am trying to install NumPy in my debian/testing linux
2.6.15-1-686.
with no numpy for debian/testing, I am left alone, since the
experimental version available by debian will result in a dependency

Turning algs for old NumPy modules into numpy code I suffer from this:
Upon further processing of returns of numpy calculations, lots of data in an apps object tree will become elementary numpy types.
First there is some inefficiency in calculations. And then you get data inflation and questionable dependencies - e.g. with pickle,ZODB,mpi's ......

Hello NG,
given this call to roots funtion from pylab
In : roots()
Out: array()
as far as I understand it stands for a0+a1*x+a2*x^2
in the above case it yields 2x^2+2x = 2x(1+x)
and the roots are 0 and -1

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
