Numerical Python Bug ?

Hi,

during a large compilation I get problems with vectors / arrays:

     print sp

delivers

    [ 100, 50,]

and

     print 0.5*sp

yields

    [ 0, 0, ]

type(sp) is "array" and type(sp[0]) is "float".

What makes me wonder is the output format. "print sp" should give

    [ 100., 50. ]

which is different from my result above...

Is there a bug in NumPy ???

One remark: the behaviour above does not happen if I enter some vectors
manually...

Yours, Uwe.
