Hi list,

we are in the process of switching our application from:

(OLD configuration)
Python 2.4.2
scipy 0.49
numpy 0.98

to:

(NEW configuration)
Python 2.5
scipy 0.52
numpy 1.0.1


When I do the following in the OLD configuration:

data = array([1,2,3,4,5,6])
stand = std(data)

the result for stand is 1.870828693386..... ,which is exactly what should
be.

However, when I do exactly the same under the NEW configuration the result
for stand is 1.70782512766.



I am clueless. Has anyone experienced the same problem? Any help
appreciated.

Oliver
