Hi,
I'm not sure if it's a bug or it's me doing something wrong.
I have two files:
test1.sage containing nothing but
print numpy.random.normal(0,(2*0.0061*0.33)^(1/2),1)
and
test2.sage containing
load "test1.sage"
I import numpy
sage: import numpy
Now
sage: load "test1.sage"
returns values always smaller than 1
thats the right distribution, the same i get when using the notebook-
interface
but
sage: load "test2.sage"
very often returns values bigger than 1,
thats a whole different distribution
My system is ubuntu-9.04-amd64 on Pentium Dual Core
sage-4.0.1 from 2009-06-06
}}}
to which Marshall responds:
{{{
I'm not sure what is happening but I would guess that at some point
the ^(1/2) gets turned into ^(0), and then your standard deviation
goes from .06... to 1. I.e., it seems like maybe the preparser
doesn't catch these nested loadings.
